23
Q

A

hepatic portal vein

24
Q

Lymphatic vessels of the abdomen will drain into

25
Sympathetic innervation to abdominal and pelvic viscera is via
Sympathetic chain -> splanchnic nerves -> mesenteric (pre-vertebral) ganglia Axons leaving the mesenteric ganglia distribute post-ganglionic sympathetic innervation to the viscera
26
Parasympathetic innervation to the abdominal and pelvic viscera is via the
Dorsal and ventral vagal nerve trunks and the pelvic nerves
27
Caudal to the diaphragm, pre-SNS neurons may synapse within
Pre-vertebral ganglia
28
Pre-vertebral ganglia are composed of
post-SNS cell bodies
29
Splanchnic nerves distribute pre-ganglionic axons to what ganglia?
Pre-vertebral (mesenteric)
30
What nerves distribute sympathetic innervation to the pelvic plexus?
Hypogastric nerve
