MICROANATOMY

Detailed explanation-1: -The epididymis is a narrow, tightly-coiled tube connecting rear of the testicles to the deferent duct (ductus deferens or vas deferens). The epididymis consists of three parts: head, body, and tail. The head of the epididymis is located on superior pole of testis. It stores sperm for maturation.

Detailed explanation-2: -Sperm cells mature primarily in the head and body of the epididymis and are stored in the tail. The epididymis receives sperm from the tubules in the mediastinum testis, the region in the testis in which all its sperm-producing tubules converge and empty.

Detailed explanation-3: -The ependyma constitute a ciliated epithelium that derives from the neuroepithelium during development and is located at the interface between the brain parenchyma and ventricles in the central nervous system (CNS).

Detailed explanation-4: -The cauda epididymis can store enough sperm for two to three normal semen samples. This is substantially less sperm than is stored in the cauda of many other species.
