Branch of the Trigeminal Nerve Third

Branch of the trigeminal nerve The third (nervus mandibulares, PNA, BNA, JNA) is a nerve that is one of the three branches of the trigeminal nerve. It passes through the lower jaw and innervates the muscles that are responsible for the movement of the lower jaw.

Branch of the trigeminal nerve The third branch arises from the large foramen in the skull, where it joins the other branches of the trigeminal nerve, and passes through the lower part of the face. It passes through and innervates the masseter muscle and also innervates other muscles associated with mandibular movement, such as the medial pterygoid muscle and the lateral pterygoid muscle.

One of the main functions of the third branch of the trigeminal nerve is to control the movements of the lower jaw. When a person eats or speaks, the Third branch of the Trigeminal nerve controls the muscles of mastication to ensure proper movement of the lower jaw and proper distribution of food in the mouth.

In addition, the Third branch of the trigeminal nerve also plays an important role in sensory function. It innervates sensory nerves in and around the mandible, which allows a person to feel touch, pressure and heat in the area.

Thus, the Third branch of the trigeminal nerve plays an important role in many functions of the mandible and ensures its proper functioning.
