NEET PG DENTAL EXAM

Detailed explanation-1: -The trigeminal nerve is the fifth cranial nerve (CN V) and the largest of the cranial nerves. Its primary function is to provide sensory innervation to the face and is divided into three main branches.

Detailed explanation-2: -The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or “cutaneous") functions.

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: -The motor root of the trigeminal nerve bypasses the trigeminal ganglion and reunites with the mandibular nerve in the foramen ovale basis cranii. Hence the V3 is the only branch which contains both sensory and motor components:the Opthalmic (V1) and Maxillary (V2) nerves contain only sensory fibres.
