GENERAL HISTOLOGY

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: -Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac. The vas deferens is between the epididymis and the urethra and connects these together.

Detailed explanation-3: -As the primitive duct migrates from the rostral end of the embryo to fuse with the cloaca (which will become the bladder), it induces a series of mesonephric tubules from the surrounding mesenchyme. These tubules will eventually form the efferent ducts that connect the testis to the epididymis.

Detailed explanation-4: -The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis. Each ductus is 30-45 cm in length and serves to transport sperms cells from the respective epididymis to the ipsilateral ejaculatory duct.

Detailed explanation-5: -Your testicles are connected to the inside of your body by a cord called the spermatic cord. Each cord contains nerves and blood vessels. The cords also contain the vas deferens, which are the tubes that move sperm to your penis, so it can leave your body in semen.
