Question

action potentials are conducted from the baroreceptors to the brain via which nerve?
multiple choice
hypoglossal nerve
glossopharyngeal nerve
accessory nerve
facial nerve
phrenic nerve

Explanation:

Baroreceptors are sensory receptors that detect changes in blood pressure. The glossopharyngeal nerve (cranial nerve IX) is responsible for conducting action potentials from baroreceptors (specifically those in the carotid sinus) to the brain. The hypoglossal nerve (cranial nerve XII) controls tongue movements. The accessory nerve (cranial nerve XI) controls neck and shoulder muscles. The facial nerve (cranial nerve VII) is involved in facial expression and taste. The phrenic nerve controls the diaphragm.

Answer:

Glossopharyngeal nerve
