Trigeminal
Trigeminal
Trigeminal (/traɪˈdʒɛmɪnəl/), from the Latin trigeminus meaning "threefold", pertains to the fifth cranial nerve, also known as the trigeminal nerve, which is responsible for sensation in the face and motor functions such as biting and chewing.
Anatomy
The trigeminal nerve is the largest of the cranial nerves. It is divided into three branches: the ophthalmic nerve, the maxillary nerve, and the mandibular nerve. Each branch is responsible for transmitting sensory information from different parts of the face to the brain.
Clinical Significance
Disorders of the trigeminal nerve can lead to conditions such as trigeminal neuralgia, a chronic pain condition that affects the trigeminal nerve. Symptoms can include severe, sudden facial pain that lasts for a few seconds to a few minutes.
