What are the three divisions of the trigeminal nerve?

The three divisions of the trigeminal nerve, also known as cranial nerve V, are indeed the Ophthalmic, Maxillary, and Mandibular divisions. This nerve is responsible for sensation in the face and certain motor functions such as biting and chewing.

The Ophthalmic division innervates the forehead, upper eyelid, and parts of the nose, providing sensory information from these areas. The Maxillary division covers the middle part of the face, including the cheeks, upper lip, and nasal cavity. Lastly, the Mandibular division supplies sensation to the lower lip, chin, and jaw area, and it also provides motor innervation to the muscles of mastication.

Understanding these divisions is essential for dental professionals as they directly relate to procedures involving local anesthesia, pain management, and dental diagnoses, making the knowledge of these an integral part of dental practices.
