Testis Section

In humans each testis weighs about 25 grams 0 875 ounce and is 4 5 cm 1 6 2 0 inches long and 2 3 cm 0 8 1 2 inches in diameter.

Testis section. The scrotum is a sac of skin that hangs from the body at the front of the pelvis between the legs. It sits next to the upper thighs just below the penis. Head body and tail.

Sample normal uninvolved testis. The septa extends from the tunica albuginea into the testicle dividing the testes into lobules. Each is covered by a fibrous capsule called the tunica albuginea and is divided by partitions of fibrous tissue from the tunica albuginea into 200 to 400 wedge shaped sections or lobes.

A typically paired male reproductive gland that usually consists largely of seminiferous tubules from the epithelium of which spermatozoa develop that contains androgen secreting leydig cells in the interstitial tissue that corresponds to the ovary of the female and in craniate vertebrates develops from the genital ridges of the embryo and that in most mammals descends into the scrotum before the attainment of sexual maturity and in many cases before birth. They re contained in a sac of skin called the scrotum. Inside the connective tissue tunic is a thin.

The testes are covered by a tough membranous shell called the tunica albuginea. The epididymis is a narrow tightly coiled tube connecting rear of the testicles to the deferent duct ductus deferens or vas deferens. The scrotum contains the testicles.

The scrotum hangs outside the body in the. Cross section of the testis the tunica albuginea is the dense white inelastic tissue immediately covering the testis beneath the visceral layer of the tunica vaginalis. The head of the epididymis is located on superior pole of testis.

It stores sperm for maturation. Sample tumor at least 1 section per centimeter including closest penetration of tunica albuginea vaginalis and epididymis. Sample grossly different areas of tumor to determine which components are present in case of potential mixed germ cell tumor.
