What are tubuli recti?

The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two …

What is the function of tubuli recti?

Both ends of a seminiferous tubule empty into the rete, and the probable function of the Sertoli cell lining in the tubuli recti is to act as a one-way valve for the passage of sperm and fluid into the rete, opening only when the pressure in the tubule rises above that in the rete and efferent ducts.

What is straight tubule of testis?

The straight seminiferous tubules are the continuation of the tubulus seminifer contortus which becomes straight just before entering the mediastinum to form the rete testis. Rather, they discharge the sperm cells produced in the convoluted seminiferous tubule into the rete testis.

What is seminiferous tubules in testis?

Seminiferous tubules are coiled (for the most part) tubules found within the testes. They are the site where spermatozoa (male gametes) are produced. The epithelial lining of the seminiferous tubule consists of Sertoli cells, which are sustentacular columnar cells, and spermatogenic cells that give rise to sperm cells.

What is the most commonly seen type of epithelium in the prostate?

What is the most commonly seen type of epithelium in the prostate? The glandular epithelium of the prostate is most often simple columnar, however a variety of types can be found.

What is the Ductuli Efferentes?

The ductuli efferentes are a series of tubules that conduct sperm from the rete testis to the epididymis. These small ducts are unique because they are the only region of the male reproductive tract that is lined by a ciliated epithelium.

What is difference in the lining epithelium of the testis?

The epithelium has a characteristic scalloped appearance that results from a lining that contains both cuboidal and columnar epithelial cells. The non-ciliated cells reabsorb testicular fluid, while the ciliated cells propel the immobile sperm to the epididymis, where they gain the ability to swim.

What kind of structure is the tubuli seminiferi recti?

Tubuli seminiferi recti. The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two structures.

Where do tubuli seminiferi enter the mediastinum?

They enter the fibrous tissue of the mediastinum, and pass upward and backward, forming, in their ascent, a close network of anastomosing tubes which are merely channels in the fibrous stroma, lined by flattened epithelium, and having no proper walls; this constitutes the rete testis.

Where is the straight tubules?

The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two structures.

Where are the seminiferous tubules located in the testes?

Seminiferous tubule in cross-section (large tubular structure – center of image) with sperm (black, tiny, ovoid bodies furthest from the outer edge of the tubular structure). H&E stain. Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa .
