Male Pelvis & Perineum: Page 4 of 7

Add the umbilical artery remnents.

These arteries are functional during the fetal and neonatal periods. They obliterate after the neonatal period. They will be removed during the next step for clarity.

Add the spermatic cord.

What structures are in the spermatic cord?

Add the internal abdominal oblique muscle.

Note that the extension of the internal abdominal oblique is the cremaster which forms the deep inguinal ring of the inguinal canal.

Add the external abdominal oblique muscle.

Note that the extension of the external abdominal oblique is the inguinal ligament which forms the superficial ring of the inguinal canal.

The inferior epigastric arteries are important landmark. Note that the spermatic cord enters the pelvis via the deep inguinal ring which is just lateral to the inferior epigastric artery.
