GROSS ANATOMY

Detailed explanation-1: -The olfactory nerve is the first cranial nerve and is instrumental in our sense of smell. The olfactory nerve contains only afferent sensory nerve fibers and, like all cranial nerves, is paired.

Detailed explanation-2: -The optic nerve is the second cranial nerve (CN II) responsible for transmitting visual information. The optic nerve contains only afferent (sensory) fibers, and like all cranial nerves is paired.

Detailed explanation-3: -CRANIAL NERVE 9 (GLOSSOPHARYNGEAL) AND CRANIAL NERVE 10 (VAGUS) CNs 9 and 10 work together to supply the musculature of the pharynx (mostly supplied by CN 10) and transmit visceral afferent information from vascular baroreceptors, and each nerve also has additional individual functions listed below.

Detailed explanation-4: -The trigeminal nerve has receptors for pungent odorants throughout the nasal and pharyngeal cavities. The glossopharyngeal and vagus nerves provide the minor chemosensory function in the pharyngeal area. The ciliated olfactory receptors are part of the olfactory neuroepithelium.

Detailed explanation-5: -The glossopharyngeal nerve (CN IX) supplies organs, muscles and other structures in your mouth and throat. It helps you taste food and sense pain in your throat.
