Review: Anatomy of the Testis
Here is what we have learned from Anatomy of the Testis:
- The testicles produce the hormone testosterone as well as sperm, the male reproductive cells.
- The epididymis is a narrow, tightly-coiled tube connecting the rear of the testicles to the deferent duct.
- The epididymis consists of three parts: head, body, and tail.
- The head of the epididymis is located on the superior pole of the testis. It stores sperm for maturation.
- The body of the epididymis is a highly convoluted duct that connects the head to the tail of the epididymis. This is where sperm mature.
- The tail of the epididymis is continuous with the deferent duct.
- The deferent duct is the excretory duct of the testis that joins the excretory duct of the seminal vesicle to form the ejaculatory duct.
- The tunica albuginea is the dense, white, inelastic tissue immediately covering the testis, beneath the visceral layer of the tunica vaginalis.
- The septa extends from the tunica albuginea into the testicle, dividing the testes into lobules.
