A)Rectus abdominis

C)Transversus abdominis
D)External oblique
E)All of these abdominal wall muscles help flex the vertebral column.

Accepted Answer

The rectus abdominis is a paired muscle that extends vertically along the anterior wall of the abdomen. It originates from the pubic symphysis and pubic crest and inserts into the xiphoid process and costal cartilages of the 5th to 7th ribs. Contraction of the rectus abdominis helps to flex the vertebral column.
