Transverse Section - Pelvis

You selected: rectus abdominus

The rectus abdominus muscle comprises the central region of the anterior abdominal wall. (It receives heavy usage during sit-ups.) The muscle is made of many segments, which produces the 'tortise shell' appearance of the abdomen in body builders. A tendinous sheath covers the rectus abdominus. This sheath is made of the aponeuroses of the three adjacent muscles on either side of the antierior abodomen - the external oblique, internal oblique, and transversus abdominus muscles. A small triangle of these muscles can be seen on either side of the rectus abdominus.
