What are the three branches of the fifth cranial nerve?

The fifth cranial nerve, also known as the trigeminal nerve, is responsible for sensation in the face and motor functions such as biting and chewing. It branches into three main divisions: the ophthalmic, mandibular, and maxillary branches.

The ophthalmic branch is involved in sensation from the forehead, upper eyelid, and parts of the nose. The maxillary branch provides sensation from the upper jaw, including the cheeks, upper lip, and the nasal cavity. The mandibular branch serves both sensory and motor functions, conveying sensation from the lower jaw and muscles related to chewing.

Understanding these branches is crucial in fields such as esthetics, where knowledge of facial anatomy aids in effective treatment and client safety. The other options do not represent the correct branches of the fifth cranial nerve, which is why they do not apply in this context.
