Study Notes
Glossopharyngeal Nerve (CN IX)
- Carries general sensory fibers for the posterior 1/3 of the tongue, soft palate, upper pharynx, and palatine tonsils
- Contains the Nucleus ambiguus responsible for branchial motor and preganglionic parasympathetic supply to the heart
- Exits the skull through the jugular foramen
- Originates in the inferior salivatory nucleus
- Carries sensory fibers for taste sensation from the posterior 1/3 of the tongue
- Carries general sensory fibers for the carotid sinus and carotid body
- Travels together with CN X and CN XI in the jugular foramen
- Has sensory, motor, and parasympathetic functions
Nucleus Ambiguus
- Responsible for the motor function of the Glossopharyngeal Nerve
- Contains motor neurons that originate from the cranial part of the nucleus ambiguus
- Supplies motor fibers to the stylopharyngeus muscle
Jugular Foramen
- Formed anteriorly by the petrous portion of the temporal bone and posteriorly by the occipital bone
- CN IX, CN X, and CN XI travel together in the jugular foramen
Other Structures
- Inferior glossopharyngeal ganglion carries general sensory fibers for the posterior 1/3 of the tongue
- Auricular branch of vagus nerve carries fibers that communicate with the vagus nerve
- Caudal spinal nucleus of CN V responsible for carrying fibers that synapse
- Occipital bone forms the posterior part of the jugular foramen
