Testis
This specimen shows different views of testes.
The testes are a pair of male gonads. They are suspended in the scrotum by the spermatic cord. The epididymis which continues as the vas deferens is seen in the specimen.
Testes:
The testes are ovoid in shape. They have two poles, two borders and two surfaces. They lie obliquely within the scrotal sacs. They consist of numerous seminiferous tubules that are made up of spermatogenic cells and sertoli cells. The Leydig cells between the seminiferous tubules secrete the testosterone hormone that is responsible for the spermatogenesis.
Epididymis:
The epididymis lies along the upper pole and the posterior border of the testis. It has an expanded head, a body and a tail. The tail of the epididymis continues upwards as the vas deferens.
Vas deferens:
The vas deferens is a continuation of the tail of the epididymis. It is a thick muscular tube, that carries the spermatozoa up to the ejaculatory ducts.
Spermatic cord:
The spermatic cord suspends the testis in the scrotum and extends from the deep inguinal ring to the posterior aspect of the testis. It consists of the vas deferens, the arteries, the pampiniform venous plexus, the nerves and the lymphatic vessels.
