Trigeminal motor function

Motor function tests for trigeminal neuralgia include the movement of the temporal muscles, internal and external pterygoid muscles. Because the masticatory muscles all stop at the mandible, under the control of the trigeminal motor, they move the temporomandibular joint, participate in chewing and speech exercises, and also participate in the expression of expressions to a certain extent. If the masticatory muscle is damaged, in addition to the above-mentioned dyskinesias, facial symptoms such as deformed jaw deformation and facial hypertrophy can also occur. In the above masticatory muscle group, the masseter muscle, the temporal muscle, and the pterygoid muscle contraction can lift the mandible (closed), and the lateral pterygoid muscles can contract at the same time, which can make the mandible forward and the lateral pterygoid muscle contraction, making the mandible Moving to one side, if the rotation on both sides is contracted, the mandible can be moved left and right.
