The muscles of the anterior abdominal wall assist in all of the following activities except:

A.  inspiration.

B.  defecation.

C.  sneezing.

D.  vomiting.

E.  parturition.


Which of the following is incorrect pertaining to the rectus abdominis muscle or rectus sheath?

A.  The linea alba separates (lies in the midline between) the two rectus muscles.

B.  The attachments (tendinous insertions) between the muscle and the anterior layer of sheath account for the abdominal definition (ripples) evident when muscular individuals tense this muscle.

C.  The posterior layer of the sheath is composed of the aponeuroses of the internal oblique and the transversalis fascia throughout the extent of the sheath.

D.  The external oblique aponeurosis contributes to the anterior wall of the sheath throughout the craniocaudal extent of the sheath.

E.  Transverse surgical incisions can be made in this muscle without resulting in muscle fiber necrosis.

The nerve supply to the muscles of the anterior abdominal wall:
