Testes: Anatomy, definition and diagram Kenhu

The Tunica Vasculosa is the vascular layer of the testis, consisting of a plexus of bloodvessels, held together by delicate areolar tissue. It clothes the inner surface of the tunica albuginea and the different septa in the interior of the gland, and therefore forms an internal investment to all the spaces of which the gland is composed The epididymis consists of a single heavily coiled duct. It can be divided into three parts; head, body and tail. Head - The most proximal part of the epididymis. It is formed by the efferent tubules of the testes, which transport sperm from the testes to the epididymis

Layers of the scrotum (mnemonic) Radiology Reference

Most males are born with two testicles, collectively known as the testes. These soft, egg-shaped organs are located inside the scrotum. They are surrounded by a number of accessory structures including the epididymis and the vas deferens. The testes are suspended from the abdomen by the spermatic cord I would like to enlist the structures that you should identify under the light microscope from testis histology slide at laboratory. #1.

Staring William Whyte The epididymal tail is attached to the testis by the proper ligament of the testis. The ligament of the tail of the epididymis attaches the testis and epididymis to the vaginal tunic and spermatic fascia. The tail of the epididymis continues craniodorsally up into the spermatic cord as the ductus deferens (vas deferens)

  1. al cavity is therefore then, normally, obliterated
  2. Testicle or testis (plural testes) is the male reproductive gland or gonad in all animals, including humans. It is homologous to the female ovary.The functions of the testes are to produce both sperm and androgens, primarily testosterone.Testosterone release is controlled by the anterior pituitary luteinizing hormone; whereas sperm production is controlled both by the anterior pituitary.
  3. Descent of the testes. Between the 3rd month of pregnancy and its end the testes become transferred from the lumbar area (ventro-medial to the mesonephros) into the future scrotum. This transfer is due to a combination of growth processes and hormonal influences ( 7 ). The gubernaculum testis also plays a decisive role in this phenomenon

Layers of the scrotal wall also get called layers of the testicles. It's kind of a misnomer but that's ok.Skin - Dartos - ESF - Cremaster - ISF - Tunica Vagi.. Internal spermatic fascia - derived from the transversalis fascia. The three fascial layers themselves are covered by a layer of superficial fascia, which lies directly below the scrotal skin. The cremaster muscle forms the middle layer of the spermatic cord fascia Tunica Vasculosa is the first thin layer of blood vessels which protects the tubular interior of each testicle from further layers of tissue. Tunica Albuginea is the next layer which is a thick, protective layer made of densely packed fibers that further shield the testes. Tunica Vaginalis is the outermost layers of tissue. It consists of three. Each testicle is covered by tough, fibrous layers of tissue called the tunica. The outer layer is called the tunica vaginalis and the inner layer is called the tunica albuginea. The testicle is divided into parts called lobules. Each lobule contains tiny U-shaped tubes called seminiferous tubules

Concentric layers of primary spermatocyte, secondary spermatocyte and spermatids are present.4. At the centre of the lumen there are cluster of sperm with long flagellated tail5. At the interstitious zone there are patches of Leydig cells presenting the endocrine part of the testes6. Sections of blood vessel are presen Testis Overview The processes vaginalis, a remnant of the peritoneal space, is lined by visceral and parietal layers of tunica vaginalis, a serous membrane. Like all serosas, the tunica vaginalis is composed of connective tissue covered by a simple squamous epithelium (mesothelium) Structure. The tunica albuginea is a layer of fibrous tissue capsule covering the testis. It is covered by the tunica vaginalis, except at the points of attachment of the epididymis to the testis, and along its posterior border, where the spermatic vessels enter the gland. It is thicker than the tunica albuginea of the ovary.. The tunica albuginea is applied to the tunica vasculosa over the. Excerpt A hydrocele is an abnormal collection of serous fluid between the two layers of tunica vaginalis of testis. It can either be congenital or acquired. Congenital hydrocele results from failure of processus vaginalis to obliterate The testes contain several important cell types that are important to understand. The first two of these are found in the germinal epithelium , the layer of the seminiferous tubule in which gamete production and development occurs

Fig. 11.1 Anatomical layers surrounding the normal testis. The shaded area between the two layers of the tunica vaginalis is the area of fluid accumulation giving rise to a hydrocele (shaded area, potential space for fluid accumulation). (Source: Sidhu PS. Clinical and imaging features of testicular torsion: role of ultra-sound The Testis is situated in every half of the scrotal sac. It is a male gonad that is homologous with the ovary in the female. Testis is one of the mobile organs of the body. It possesses the various functions, such as - generation of spermatozoa and secretion of testosterone or dihydrotestosterone (a male hormone), it is responsible for the development and maintenance of the secondary sex.

Testis: convoluted tubules. The convoluted portions of the seminiferous tubules form the main mass of the testis and are the site of spermatogenesis. Stratified seminiferous epithelium lining these tubules contains Sertoli cells and several layers of germ cells. A basal lamina and a thin layer of connective tissue surrounds each tubule. 600x There are three layers to the tunica, the tunica vasculosa, tunica albuginea and tunica vaginalis. The tunica vasculosa is the inner layer of the tunica and consists of blood vessels and connective tissue. It is covered by the tunica albuginea and facilitates blood supply to the testes

  1. Paired ovals, the testes are each approximately 4 to 5 cm in length and are housed within the scrotum (see this figure). They are surrounded by two distinct layers of protective connective tissue (Figure \(\PageIndex{1}\): Anatomy of the Testis). The outer tunica vaginalis is a serous membrane that has both a parietal and a thin visceral layer
  2. al wall..
  3. Each testicle is wrapped in two layers of protective, fibrous tissue. The inner layer is a tough layer called the tunica albuginea which protects the testicle. The second layer of tissue, called the tunica vaginalis, is the same layer that lines the scrotum. This allows the testicle to move freely inside the scrotal sac without much friction
  4. The testes and epididymis are paired structures, located within the scrotum. The testes are the site of sperm production and hormone synthesis, while the epididymis has a role in the storage of sperm. In this article, we shall look at the anatomy of the testes and epididymis - their structure, vasculature, innervation and clinical correlations
  5. The double layer of simple squamous epithelium and mesentery directly covering the testes and apposed to the tunica albuginea is the tunica vaginalis. The parenchyma of the testicle is divided into lobules by loose connective tissue bands (septuli testes)
  6. a. Peritoneum that accompanied the testis in its embryological, retroperitoneal descent. b. Lines the interior surface of the scrotum (parietal layer) c. Covers anterior surface and sides of testis but not its posterior surface (visceral layer) 3. Tunica albuginea - a layer of dense connective tissue beneath the tunica vaginalis
  7. Beneath the tunica vaginalis is the tunica albuginea, a tough, white, dense connective tissue layer covering the testis itself. Not only does the tunica albuginea cover the outside of the testis, it also invaginates to form septa that divide the testis into 300 to 400 structures called lobules

Testicular torsion means that your testicle has rotated in the scrotum. This twisting of the spermatic cord cuts off blood supply, nerve function, and sperm transport to your testicle Once the testicle is delivered, the testis-sparing portion should begin. Intraoperative ultrasound should be used to identify the mass, rule out other masses and create a surgical plan. The outer layer of the testicle (the tunica albuginea, which houses the tubules of the testicle) is opened and the mass is removed, often with a small. Testis The testis remains covered by: Tunica vaginalis- The outermost covering (peritoneal covering of the testisandepididymis). It has a parietal and visceral layer. The parietal layer remains adhered to the scrotum while the visceral layer adheres to the capsule of the testis. The space between the these two layers is called the vaginal cavity Rete testis: anastomosing network of tubules, lined with single-layer isoprismatic epithelium. The seminiferous tubules start and end at the rete testis. The germinal epithelium suddenly ends with begin of the rete testis, forming a kind of valve to prevent the backflow of spermatozoa. Histology of the epididymis and vas deferen Testis, plural testes, also called testicle, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormones.In humans the testes occur as a pair of oval-shaped organs. They are contained within the scrotal sac, which is located directly behind the penis and in front of the anus.. Anatomy of the teste

The epididymis is basically a long tube that stores and transports the maturing spermatozoa. It is divided into a head, body, and a tail. The head of the epididymis is firmly attached at the cranial end of the testis. The body lies on the dorsolateral surface, while the tail is attached to the caudal end of the testis TESTIS Slide 27 Testis, epididymis, vas deferens, infant. Examine the slide w/o the microscope and note the testis, head of epididymis and vas deferens. With low power objective identify the thick dense regular connective tissue capsule surrounding the testis; this is the tunica albuginea.With higher power note that it is covered by mesothelium, the visceral layer of the processus vaginalis

These vaginal layers contain nonstriated smooth muscle cells that transport spermatozoa toward the rete testis and into the epididymis. The visceral layer is closely adherent to the tunica albuginea, a fibrous capsule that covers the testis and extends into the gland, dividing it into lobules (3,6) The anatomic layers surrounding the normal testis. The blue shaded area between the two layers of the tunica vaginalis is the area of fluid accumulation, which gives rise to a hydrocele. (From Sidhu PS. Clinical and imaging features of testicular torsion: role of ultrasound Tunica vaginalis Anatomy. This serous pouch comprises of two layers of serous membranes that cover the Tunica vaginalis albuginea - a layer of the fibrous substance that enwraps the testes. It extends 1 cm into the spermatic cord. The inner surface of the sac is smooth and covered by a stratum of simple cuboidal mesothelial cells

These coverings of the testes are; tunica vaginalis, internal spermatic fascia, cremasteric fascia, external spermatic fascia, and the dartos muscle from deep to superficial layers. The deepest covering of the testis is the tunica albuginea, which represents the capsule of the testis and is not acquired from the abdominal wall ANATOMICAL POSITION: 3. STRUCTURE OF THE SCROTUM: 4.

May result in infarction, rupture, or torsion of testis The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testes in males and the ovaries in females. The gonads initially develop from the mesothelial layer of the peritoneum.. The ovary is differentiated into a central part, the medulla, covered by a surface layer, the germinal epithelium.The immature ova originate from cells from.

The tunica has three layers: the tunica vasculosa, the inner layer that consists of blood vessels and connective tissue; the tunica albuginea, which encases the testes and connects to the fibers. The testis is surrounded by a thick layer of loose connective tissue, the spermatic fascia, that's formed by the fusion of two developmentally distinct layers, the internal and external spermatic fasciae, that are derived from different layers of the abdominal wall. We'll draw the spermatic fascia aside

The testes are the male reproductive glands that are about 4.5 cm long, 2.5 cm wide and 3 cm thick and surrounded by three layers of tissues namely, tunica vaginalis, tunica albuginea, and tunica vasculosa. A testis is composed up to 900 coiled seminiferous tubules in which the sperms are formed The tunica propria contains several layers of fibroblasts and myoid cells that probably assist in expelling spermatozoa from the tubules. The seminiferous epithelium consists of cells of the spermatogenic lineage, stacked in 4-8 layers, and supporting Sertoli cells. The cells in the spermatogenic series represent various stages in the. It is the middle layer formed by fibrous connective tissue. It is the innermost layer formed of delicate connective tissue, supporting a network of blood capillaries. ii. Each testis contains about 200-300 tubules called seminiferous tubules. iii. These are lined by a single layer of cuboidal germinal epithelium which undergo Scan along the tunica albuginea of the testis, looking for a region where it thickens and is permeated by a network of flattened channels in the dense connective tissue. This portion of the testis is known as the mediastinum; the network of channels is the rete testis and is probably best seen in slide #270 or #275 . Observe that the rete.

Testes: Anatomy, Function, and Treatmen

The descending testes are supported by a layer of the peritoneum (tunica vaginalis), which is normally secured to the superior and inferior posterior pole of the testis. With the assistance of the gubernaculum at the lower pole, the testes are pulled into the scrotum Testicular sperm extraction (TESE) is a procedure involving the excision of seminiferous tubules from the testicle to obtain sperm for reproduction. TESEs are performed for a number of reasons including obstructive azoospermia (absence of sperm), spermatogenic failure, or patients with cancer for cryopreservation. Men with azoospermia from obstruction such as a history of vasectomy o Hydroceles are acquired or congenital serous fluid collections between the layers of the tunica vaginalis surrounding a testis or spermatic cord.They are the most common form of testicular enlargement and present with painless enlargement of the scrotum.On all modalities, hydroceles appear as simple fluid, unless complicated by infection or hemorrhage This layer forms a sac that lines the scrotum and is closely apposed to the visceral vaginal tunic, the outer layer of the testis. The vaginal cavity is the space between the parietal and visceral layers of the vaginal tunic. It normally contains a very small amount of viscous fluid to allow some free movement of the testis within. The vaginal. vascular layer of testis. [TA] innermost of three coats (with tunicae vaginalis and albuginea) investing the testis, consisting of a vascular plexus in a delicate loose connective tissue matrix that covers the internal aspect of the tunica albuginea and extends deeply, covering the septa and therefore surrounding the lobules of the testis

Testis Histology - Complete Guide to Learn Histological

Because the testis form in abdominal cavity, and then descends into scrotal sac, the layers of ab wall accompany this trip, and so the same layers can be seen in both spermatic cord, and scrotum. Layers of Ab wall are continuous w/ layer of Spermatic cord: Contents of Spermatic cord: 1. Ductus deferens - originates from epididymis & carries. Hydrocele is a collection of fluid between the visceral and parietal layers of the tunica vaginalis that may form in the setting of abnormal fluid secretion, trauma, inflammation, or ischemia. In the setting of a sudden large hydrocele, the pressure of the fluid can exceed the pressure of the testicular vasculature, resulting in testicular. Both components are arranged in alternating layers surrounding seminiferous tubules. In spring the lamina propria of lacertilian testis shows 1-5 layers of myoid cells which are rich in 50-70 A filaments and exhibit plasmalemmal and intracellular dense patches, smooth vesicles along the cell membrane and a concentration of organelles in a.

Orchiectomy (testicle removal) is the removal of one or both testicles due to underlying pathology. Testicular cancer, undescended testicles, or other pathologies are some of the causes that may warrant a removal of the testicle. During the testicle removal procedure one or both testis are removed without any damage to the penis or the scrotum Histology of Testis: Externally, the testis is covered by three layers. These are: a. Tunica vaginalis: It is the outermost incomplete peritoneal covering made up of connective tissue and epithelium. b. Tunica albuginea: It is the middle layer formed by collagenous connective tissue. c. Tunica vasculosa/vascularis: It is the innermost layer Introduction. The adult Drosophila testes are a pair of coiled tubes in the abdomen. At the apical tip of the testis, cells are divided and differentiated to spermatid. At the end of the tip, there is a stem cell niche known as proliferation center, where the stem cell is maintained and the differentiation and proliferation is regulated (Hardy et al., Reference Hardy, Tokuyasu, Lindsley and. The parietal layer lies against the scrotal wall; the visceral layer envelops all but the posterior portion of the testicle. 1 The tunica albuginea surrounds the testicle; however, this is not normally visible under ultrasound unless fluid surrounds the testicle (Figure 1). The epididymis is an elongated, crescent-shaped structure that measures.

Right primary testicular tumor was diagnosed and the patient underwent right inguinal orchiectomy.

These two layers of peritoneum cover the testes within the scrotum and are seperated by the vaginal cavity. Once the testes have descended into the scrotum the inguinal canal contracts behind them to keep them in place. The gubernaculum regresses and leaves behind remnants which can be found in the adult; the proper ligament of the testis and. These structures descend into the scrotum and become fused with the posterior layers of the scrotum, providing an anchor which prevents the testis from rotating. At 37 to 40 weeks (full term), the processus vaginalis closes, eliminating any communication between the peritoneum and the inguinal canal or scrotum Testosterone is important for creating and maintaining male physical traits during and after puberty and for spermatogenesis. 2 Testes produce up to 12 trillion sperm over the course of a male's lifetime, with about 400 million released with each ejaculation. 1.

The testis is returned to the scrotum and is anchored to the inside of the scrotum with three sutures to prevent later torsion or twisting of the testis. A rubber drain may be left in the scrotum and the incision closed in layers by suturing This descent of the testis in males creates an inherent weakness in the abdominal wall at the inguinal canal. This weakness is important in the development of inguinal hernias. During normal testicular descent, the testis migrates caudally and traverses through various layers of the abdominal wall to end up in the scrotum An abnormal amount of fluid between the 2 layers surrounding the testis is called a hydrocele, the most common cause of scrotal enlargement. Acquired hydrocele may form as a reaction to tumor, infection, or trauma. It also may be idiopathic, resulting from excessive fluid production or failure of the mesothelial lining to reabsorb the fluid.. Composed of tissues from one or more germinal layers. May be composed of differentiated mature tissue or immature, embryonic-type tissue. Often part of a mixed GCT. In contrast to ovary, pretty much all teratomas in postpubertal testis are malignant!

Scrotum and Coverings of Testis - WikiLecture

The testes are encased in two distinctive layers of tissue known as tunics. TESTES STRUCTURE The outer tunic is a thin layer known as the tunica vaginalis. When the testicles descend, a layer of thin serous peritoneum drops as well, creating this outer layer. The inner layer is tougher, made from a fibrous membrane A testicle hernia is a type of inguinal hernia in which a loop of bowel pushes its way into the scrotum, causing a distinctive lump. Inguinal hernias in general tend to be more common in men than in women because of the way in which male fetuses develop, but testicle hernias are comparatively rare. Like other hernias, the only way to repair a. This incision facilitates access to both the testicle and the inguinal canal. The incision is carried down to the external oblique fascia (the outermost layer of the body wall). The external oblique creates a tunnel through which the spermatic cord travels — a hernia can form when there is weakness in these layers of the body wall Benign dilatation of the efferent ductules in the rete testis or head of the epididymis. Usually idiopathic but cystic dilation from outflow obstruction may play a role. Diagnose by ultrasound demonstrating a well defined simple cyst. Lined by cuboidal, columnar, ciliated or flattened epithelium. Cystic contents often contain spermatozoa

This portion of the testis is known as the mediastinum; the network of channels is the rete testis and is probably best seen in slide 270 View Image or slide 275 View Image Observe that the rete testis is lined with a cuboidal (or sometimes low-columnar) epithelium and you may see occasional microvilli Spermatic cord, either of a pair of tubular structures in the male reproductive system that support the testes in the scrotum.Each cord is sheathed in connective tissue and contains a network of arteries, veins, nerves, and the first section of the ductus deferens, through which sperm pass in the process of ejaculation.The cords extend from the testes to the inguinal rings (openings at the. The genital ducts. The looped seminiferous tubules in the testes are connected to the genital duct system which transports the spermatozoa and fluid component of the semen to the outside.. This duct system is made up of the tubuli recti (short straight tubules connected to the seminiferous tubules), the rete testis - which is found in the mediastinum testis Scrotal/Testicle Shape: A common cause of low fertility in bull is abnormal testicle and scrotal sac development. The testicles should be symmetrical, nearly the same size, and freely movable in the scrotum. Small size or degeneration often affects one testicle only and is a serious finding. There ar three basic shapes in beef bulls Testicular torsion: The spermatic cord can twist, displacing the testicle and potentially leading to obstruction of blood flow, which can cause loss of the testicle if not properly corrected. This condition is a surgical emergency that needs to be urgently addressed. Undescended testes: Usually diagnosed during childhood, this condition occurs when one or both testes remain in the abdomen.

The testis is enveloped by layers of white fibrous connective tissue called the tunica vaginalis and the tunica albuginea. The tunica albuginea is the visceral layer that covers the testis, and the tunica vaginalis is the parietal layer that lines the hydrocele sac. The tunica albuginea extends inward posteriorly to form the mediastinum testis. Accompanied by thinning of the seminiferous epithelium (but usually with normal number of germ cell layers present) Increased testis weight usually present. May be accompanied by dilated rete testis, dilated efferent ducts, or sperm stasis/sperm granulomas in the efferent ducts Three layers of the spermatic cord are picked up from three layers of the abdominal wall: 1)internal spermatic fascia, 2)cremaster muscle and fascia, and 3)external spermatic fascia.

Testicular trauma is relatively uncommon. However, severe injuries can result in many complications and should be carefully diagnosed and managed. We present a case of testicular fracture diagnosis made by ultrasonography. The surgical exploration revealed the fracture as well as complete rupture of the tunica albuginea. Testicular rupture is the disruption of the tunica albuginea, while. Choriocarcinoma: This is a very rare and fast-growing type of testicular cancer in adults. Pure choriocarcinoma is likely to spread rapidly to other parts of the body, including the lungs, bones, and brain. More often, choriocarcinoma cells are seen with other types of non-seminoma cells in a mixed germ cell tumor 6. Hydroceles. When a layer of fluid collects in a sac around the testicle, it's called a hydrocele.Up to 10 per cent of male newborn babies are born with a hydrocele, though they usually settle. The tunica albuginea may be invaded and there may be distortion of the testicular contour.
