Sigmoid colon
The faliciform ligament is associated with the anterior surface of which of the following abdominal organs
Liver
Cell bodies of which type of neurons comprise the superior mesenteric ganglion
Sympathetic visceral efferent neuron cell bodies only
Autonomic fibers innervating epinephrine releasing cells of the adrenal medulla originate from pre-ganglionic neuron cell bodies located within which one of the following portions of the nervous system

The left tenth rib
Which structure is NOT located in the posterior abdominal wall?
Ileum
Which of the following arteries is not part of the superior mesenteric artery
