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. The different branches are the ophthalmic (V1), maxillary (V2), and mandibular (V3) nerves.
Detailed explanation-2: -Trigeminal neuralgia is sudden, severe facial pain. It’s often described as a sharp shooting pain or like having an electric shock in the jaw, teeth or gums. It usually happens in short, unpredictable attacks that can last from a few seconds to about 2 minutes. The attacks stop as suddenly as they start.
Detailed explanation-3: -Sensation on the face is innervated by the trigeminal nerves (V) as are the muscles of mastication, but the muscles of facial expression are innervated mainly by the facial nerve (VII) as is the sensation of taste.
