In one of the lower abdominal quadrants of the male cadaver, locate the spermatic cord emerging from the external oblique muscle through the superficial (external) inguinal ring. You will examine the components of the spermatic cord in Exercise Four.

The spermatic cord is identified by its connection with the testes. The inguinal canals are more obscure in the female because there are fewer structures passing through them. Look between the anterior iliac spine and the pubic symphysis.

Inguinal ring and the associated structures.

Reflect the external oblique. With a probe, gently confirm the continuity of the canal through the external and internal oblique, and through the transversus and the transversalis fascia. Note how these muscles form arches and thus the "roof" of the inguinal canal. Now through the opening in the linea alba, and into the abdominal cavity, reflect the abdominal wall laterally, and find the deep inguinal ring formed by the transversalis fascia. Note how the spermatic cord, once passing through the deep ring, disbands into its various components. (Figure 3-12)

See if you can identify parietal peritoneum as it lines the innermost surface of the abdominal wall. This is a thin transparent membrane.
