PATHOLOGY

Detailed explanation-1: -The epididymis is a duct-like organ that connects the testis to the vas deferens and is comprised of four anatomical regions: the initial segment, caput, corpus, and cauda. Sperm maturation occurs during epididymal transit by the interaction of sperm cells with the unique luminal environment of each epididymal region.

Detailed explanation-2: -Epididymides. The epididymides are a pair of long tubular structures attached to the dorsal surface of the testes: one epididymis per testis. Each is divided into a head (caput), body (corpus) and tail (cauda).

Detailed explanation-3: -Head or caput epididymis – It is the broad portion of the epididymis present above the testes posteriorly. Body or corpus epididymis – It is the long coiled tube, where sperms mature. Tail or cauda epididymis – It stores the mature sperm and is connected to the vas deferens.
