NEET PG DENTAL EXAM

Detailed explanation-1: -The trigeminal nerve is the largest of the cranial nerves and provides sensory and motor innervation to the muscles of mastication. [1] More specifically, the sensory information conducted by this nerve includes touch, pain, and temperature.

Detailed explanation-2: -The dorsal most branch of the trigeminal nerve is the ophthalmic nerve, also called CN V1. This branch carries only sensory information to the brain. It innervates the “upper third” of the face, receiving sensory input from the scalp, forehead, upper eyelid, eyeballs, and the nasal cavity.

Detailed explanation-3: -The trigeminal nerve is one set of the cranial nerves in the head. It is the nerve responsible for providing sensation to the face. One trigeminal nerve runs to the right side of the head, while the other runs to the left. Each of these nerves has three distinct branches.

Detailed explanation-4: -Spinal trigeminal nucleus. The spinal trigeminal nucleus represents pain-temperature sensation from the face. Pain-temperature fibers from peripheral nociceptors are carried in cranial nerves V, VII, IX and X. On entering the brainstem, sensory fibers are grouped and sent to the spinal trigeminal nucleus.
