How many branches does the mandibular branch V3 of the Trigeminal nerve have?

The mandibular branch, also known as V3 of the Trigeminal nerve, has four main branches. These branches serve various functions related to both sensory and motor innervation.

The primary branches are the inferior alveolar nerve, which provides sensation to the lower teeth; the lingual nerve, which supplies sensation to the anterior two-thirds of the tongue; the buccal nerve, which innervates the skin and mucous membrane of the cheek; and the auriculotemporal nerve, which innervates the area around the ear and carries postganglionic parasympathetic fibers to the parotid gland.

Each of these branches plays a critical role in facial sensation and movement, especially in the context of chewing and oral function. Understanding the specific roles and pathways of these branches is essential for diagnostics and treatment in dental practice.
