Question
Which statement(s) about the INFERIOR hypogastric plexus is/are correct?I. The nerve fibers are sympathetic and parasympatheticII. The nerve fibers run over the aortic bifurcationIII. It is located in the midlineIV. The plexus is located cranial to the pelvic floor musclesV. It is located superficial to the superior hypogastric plexusAll of the mentioned statementsOnly II, III and IVOnly II and IVOnly I and IVOnly I, II and III
Solution
The correct answer is "Only I and IV".
Explanation:
I. The nerve fibers are sympathetic and parasympathetic - This is correct. The inferior hypogastric plexus carries both sympathetic and parasympathetic fibers.
II. The nerve fibers run over the aortic bifurcation - This is incorrect. The nerve fibers of the inferior hypogastric plexus do not run over the aortic bifurcation.
III. It is located in the midline - This is incorrect. The inferior hypogastric plexus is not located in the midline, but rather on either side of the rectum in the pelvis.
IV. The plexus is located cranial to the pelvic floor muscles - This is correct. The inferior hypogastric plexus is located above (or cranial to) the pelvic floor muscles.
V. It is located superficial to the superior hypogastric plexus - This is incorrect. The inferior hypogastric plexus is located deep (or inferior) to the superior hypogastric plexus, not superficial.
