Quizplus · Accepted Answer

Parasympathetic preganglionic neurons travel in both cranial and pelvic nerves. Cranial nerves involved include the oculomotor nerve (III), the facial nerve (VII), the glossopharyngeal nerve (IX), and the vagus nerve (X). Pelvic nerves refer to the sacral part of the spinal cord (S2-S4), which gives rise to the pelvic splanchnic nerves that innervate the lower half of the body.
