Where is the taste nerve located in the brain?

Located in the jugular foramen . Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus. Some sensation is also relayed to the brain from the palatine tonsils. This nerve is involved together with the vagus nerve in the gag reflex .

Where are the sensory nerves located in the head?

Hypogloassal Nerve The cranial nerves contain the sensory and motor nerve fibers that innervate the head. The cell bodies of the sensory neurons lie either in receptor organs (e.g., the nose for smell, or the eye for vision) or within cranial sensory ganglia, which lie along some cranial nerves (V, VII–X) just external to the brain.
