Cranial Nerve 5- Motor
The motor division of CN 5 supplies the muscles of mastication (temporalis, masseters, and pterygoids). Palpate the temporalis and masseter muscles as the patient bites down hard. Then have the patient open their mouth and resist the examiner's attempt to close the mouth. If there is weakness of the pterygoids the jaw will deviate towards the side of the weakness. The last test for this nerve is testing for a jaw jerk, which is a stretch reflex. Have the patient slightly open their mouth then place your finger on their chin and strike your finger with a reflex hammer. Normally there is no movement. If there is a jaw jerk it is said to be positive and this indicates an upper motor neuron lesion.
