external oblique. the external oblique muscles are paired superficial muscles that make up the (1. ) walls of the abdomen. their fibers run
downward and medially from the last eight ribs and insert into the ilium. like the rectus abdominis, they flex the vertebral column, but they also (2.
) the trunk and bend it laterally.
internal oblique. the internal oblique muscles are paired muscles deep to the external obliques. their fibers run at right angles to those of the ( 3.
) obliques. they arise from the iliac crest and insert into the last three ribs. their functions are the same as those of the external obliques.
transversus abdominis. the deepest muscle of the abdominal wall, the ( 4. ) abdominis has fibers that run horizontally across the
abdomen. it arises from the lower ribs and iliac crest and inserts into the pubis. this muscle compresses the ( 5. ) contents.

Explanation:

The external oblique muscles make up the lateral walls of the abdomen. They can rotate the trunk and bend it laterally. The internal oblique fibers are at right - angles to the external obliques. The transversus abdominis is the deepest abdominal muscle and compresses the abdominal contents.
