Q

What are the 4 main muscles of the abdominal wall and where are they?

A

Rectus abdominus is down center of abdomen.
Laterally, external oblique, with fascia wrapping over rectus abdominus forming the anterior rectus sheath. The posterior section folds and becomes the inguinal ligament.
The internal oblique is deep to the external, fascia splits and courses on either side of rectus abdominus helping to form the rectus sheath.
Posteriorly is transverse abdominus, fascia extends behind rectus abdominus.

Q

Describe the difference in the rectus sheath anteriorly vs at the arcuate line and below

A

Superiorly we have aponeurosis on both sides of the rectus sheath. Below the arcuate line all three aponeurosis are above the sheath, providing less protection to force on the pelvis (c.c. hernias!)
