Trigeminal Nerve
Nervio trigémino
What are the branches of the trigeminal nerve?
According to the National Institute of Neurological Disorders and Stroke (NINDS), the trigeminal nerves have three branches. The ophthalmic (upper) branch supplies sensation to most of the scalp, forehead, and front of the head. The maxillary (middle) branch supplies sensation to the cheek, upper jaw, top lip, teeth and gums, and side of the nose. The mandibular (lower) branch supplies nerves to the lower jaw, teeth and gums, and bottom lip.
What is trigeminal neuralgia?
NINDS describes trigeminal neuralgia (TN), also known as tic douloureux, as a type of chronic pain disorder that involves sudden attacks of severe facial pain, and says it affects the trigeminal nerve. MedlinePlus lists pressure on the trigeminal nerve from a swollen blood vessel or tumor and injury to the nerve among the possible causes, and adds that often no exact cause is found.
What it means
The trigeminal nerve is the main sensory nerve of the head and face and the motor nerve of the muscles used in chewing; the National Cancer Institute (NCI) dictionary also calls it the fifth cranial nerve. The National Institute of Neurological Disorders and Stroke (NINDS) describes the trigeminal nerves as a pair of cranial nerves that connect the brain and brain stem to different parts of the face, with three branches that send and receive sensations from the upper, middle, and lower portions of the face. MedlinePlus says the nerve carries the sensations of touch and pain from the face, eyes, sinuses, and mouth to the brain. Trigeminal neuralgia (TN) is a nerve disorder that causes a stabbing or electric shock-like pain in parts of the face.
