Detailed explanation-1: -The rectus abdominis compresses the abdominal viscera, prevents herniation, and stabilizes the pelvis during ambulation. Pyramidalis-vertical muscle shaped like a triangle. It is located superficial to the rectus abdominis and located at the base of the pubic bone.

Detailed explanation-2: -External Oblique This is the most superficial, largest, and thickest of the 3 anterolateral abdominal wall muscles. It originates from the lower 7 ribs and runs obliquely from superior/lateral to inferior/medial (hands in pocket orientation) to insert on the anterior one-half of the iliac crest.

Detailed explanation-3: -The name ‘rectus abdominis’ means ‘straight abdominal’, and is indicative of the parallel direction the fibres of the muscle take as they pass from their origin to their point of insertion. The muscle has a strap-like shape, and is narrower inferiorly, widening as it passes superiorly.

Detailed explanation-4: -3 flat muscles on the anterolateral side arranged from superficial to deep; external abdominal oblique, internal abdominal oblique, transversus abdominis.
