Question

which plexus does not receive innervation from the vagus nerve?
○ inferior hypogastric plexus
○ cardiac plexuses
○ abdominal aortic plexus
○ pulmonary plexuses

Explanation:

The vagus nerve (CN X) innervates structures in the thoracic and abdominal cavities (like cardiac, pulmonary, and abdominal aortic plexuses) via parasympathetic fibers. The inferior hypogastric plexus is part of the pelvic plexus, innervated by pelvic splanchnic nerves (parasympathetic from S2 - S4) and sympathetic fibers, not the vagus nerve.

Answer:

A. inferior hypogastric plexus
