Detailed explanation-2: -Glossopharyngeal nerve (CN IX) Glossopharyngeal nerve is another multimodal nerve. It originates from the brainstem and leaves the skull through the jugular foramen. Its fibers originate from four nuclei; nucleus ambiguus, inferior salivatory nucleus, nuclei of solitary tract and spinal nucleus of trigeminal nerve.

Detailed explanation-3: -Glossopharyngeal nerve is a mixed nerve that consists both of the motor and sensory fibers that rise from its nuclei. This nerve has altogether 4 nuclei that are located in the medulla oblongata: The ambiguous nucleus. The inferior salivary nucleus.

Detailed explanation-4: -Mixed cranial nerves are a group of cranial nerves that consist of sensory and motor nerve fibers. There are four such nerves in our peripheral nervous system namely the Trigeminal nerve (CN V), Facial nerve (CN VII) Glossopharyngeal nerve (CN IX), and Vagus nerve (CN X).

Detailed explanation-5: -The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.
