Question

Information from chemoreceptors travels to the brain via the ________ nerves.
A) trigeminal
B) hypoglossal
C) vagus
D) glossopharyngeal
E) vagus and glossopharyngeal

Accepted Answer

Chemoreceptors, which detect chemical changes in the blood such as CO2 and O2 levels, primarily send information to the brain through the vagus and glossopharyngeal nerves. The vagus nerve (cranial nerve X) carries information from chemoreceptors in the aortic body, while the glossopharyngeal nerve (cranial nerve IX) carries information from chemoreceptors in the carotid body.
