The efferent ductules (ductuli efferentes) are a series of parallel thin, delicate tubules that connect the rete testis to a single tube, the epididymis.

What are Ductuli Efferentes?

The efferent ductules (ductuli efferentes) are a series of parallel thin, delicate tubules that connect the rete testis to a single tube, the epididymis.

Is Ductuli Efferentes and Vasa Efferentia same?

Ductuli efferentes is that part of vasa efferentia which lies inside testis and is hence part of intra testicular duct system.. while remaining part is simply called vasa efferentia, which is present outside testis, and hence a part of extra testicular duct system..

Is Vasa Efferentia a part of testis?

Option A: The seminiferous tubules of the testis open itself into the vasa efferentia. This opening passes through the rete testis. The vasa efferentia then leaves the testis and opens up into the epididymis which is located close to the posterior surface of each of the testis.

Where is Vasa Efferentia in the male reproductive system?

Rete testis connects the seminiferous tubules of testis to vasa efferentia which opens into the epididymis. – Epididymis is situated in the posterior part of the testis which opens into the vas deferens. Vas deferens opens into the urethra through an ejaculatory duct.

What is mediastinum testis?

The mediastinum testis is a network of fibrous connective tissue that extends from the top to near the bottom of each testis. It is wider above than below. Numerous imperfect septa are given off from its front and sides, which radiate toward the surface of the testes and are attached to the tunica albuginea.

What is the function of rete testis?

A network of small tubes in the testicle that helps move sperm cells (male reproductive cells) from the testicle to the epididymis.

What is the difference between vas deferens and Vasa Efferentia?

Vasa efferentia arise from the rete testis and open into the epididymis and conduct spermatozoa out from the testis, whereas vas deferens is a partially coiled thick muscular tube arising from each epididymis. This tube conducts spermatozoa from the epididymis to the base of the urinary bladder.

What is rated testis?

The rete testis (/ˈriːti ˈtɛstɪs/ REE-tee TES-tis) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the counterpart of the rete ovarii in females.

What is the difference between Vasa Efferentia and vas deferens?

What is the meaning of Vasa Efferentia?

Definitions of vasa efferentia. the several highly convoluted tubules that lead from the rete testis to the vas deferens and form the head of the epididymis.

What is the Vasa Efferentia?

What is Vasa Efferentia and its function?

About Vasa efferentia Function. Important function is to be part of the conduites for sperms, which make a pathway and help the transportation of sperms from rete testis to the epididymis (a tube that connects a testicle to a vas deferens; Pic. 1, 2) thanks to smooth muscle contraction.

What are efferent ducts in the testes?

The efferent ducts (or efferent ductules or ductuli efferentes or ductus efferentes or vasa efferentia) connect the rete testis with the initial section of the epididymis. There are two basic designs for efferent ductule structure: a) multiple entries into the epididymis, as seen in most large mammals.

Where do the ductuli efferentes come from?

The ductuli efferentes emerge from the dorso-superior margin of each testis. They originate from the rete testis and gradually fuse to form the ductus epididymis.

What is the structure of the ductuli efferentes and epididymis?

The ductuli efferentes and the tube of the epididymis have walls of considerable thickness, on account of the presence in them of muscular tissue, which is principally arranged in a circular manner. These tubes are lined by columnar ciliated epithelium

What are the two basic designs for efferent ductule structure?

There are two basic designs for efferent ductule structure: 1 a) multiple entries into the epididymis, as seen in most large mammals. In humans and other large mammals, there are… 2 b) single entry, as seen in most small animals such as rodents, where by the 3–6 ductules merge into a single small… More
