The dissection of the abdominal wall includes the inguinal canal. Although the region is usually best demonstrated in male cadavers, you are expected to understand the anatomy in both males and females. Be sure and get around to other dissections.

Basic concepts:
You may wish to review the basic concepts for the abdominal wall at this time. The link opens a new window which you will need to close to return to this page.

Specific Learning Objectives:

1. Describe the surface anatomy and projection of viscera on the anterior abdominal wall and back.
2. Explain the relationships of the fascial layers to the muscles and peritoneum.
3. Demonstrate the extent of the inquinal canal, its boundaries and contents.
4. Identify anatomic structures in radiographic studies including X-ray, CT scans and MRI films.

Difficult parts of the dissection:

1. Dissecting the layers of abdominal muscles is best done laterally where the muscles are thicker. See Step 2.
2. Demonstrating the inguinal ring and related structures is easier in the male because of the larger spermatic cord. Palpating the pubic tubercle and following the spermatic cord proximally from the scrotum will help you to delineate the superficial ring. See Step 4 for detailed instructions.
