Male External Genitalia/Spermatic Cord - Whole View

This seems to be an appropriate time to inspect the male external genitalia, and the scrotum, testes and spermatic cord. Begin by examining the testes housed in the scrotum. Note how each scrotum is divided into two pouches by a median septum. (The scrotum is normally divided into two pouches, however, the Visible Human Male cadaver has only the left testicle. For this reason, there is only one pouch)

Examine the testes and find the head of the epididymis. Follow the epididymis until it becomes a definite single tubular ductus deferens.

At this point we should examine the elements of the spermatic cord. We have already found the ductus (vas) deferens. It lies on the posterior aspect of the spermatic cord. The testicular artery, which runs with the pampiniform plexus of veins is the other major component of this cord.

There are, of course, lymphatics and small autonomic nerves included in the cord as well.

It is important to realize that the spermatic cord also includes all of the layers of the abdominal wall that have been pushed ahead of the testes. These layers surround the inner components of the spermatic cord.

Follow all of these cord components from the testes to the superficial inguinal ring.

Now look on the inside of the abdominal wall and find the same structures at the deep inguinal ring. Notice how the ductus swings immediately medial, hooking around the lateral side of the inferior epigastric artery, while the testicular artery and vein take a very different superior headed route.

Turn your attention to the primary structure of the male external genitals. Identify the penis and its three erectile tissue shafts: the paired lateral and outer corpora cavernosa attached to the inferior pubic rami and the singular corpus spongiosum (housing the urethra), which ends distally as the glans penis.
