The jaw jerk reflex is a muscle stretch reflex in which both the sensory and motor nerve fibers are contained in the trigeminal nerve. It is primarily mediated by proprioceptive impulses from the muscles of mastication to the motor trigeminal nucleus. The last test for this nerve is testing for a jaw jerk, which is a stretch reflex. The reflex can help distinguish an upper cervical cord compression from lesions that are above the foramen magnum. The jaw jerk reflex or the masseter reflex is a stretch reflex used to test the status of a patient's trigeminal nerve (cranial nerve v) and to help distinguish an upper cervical cord compression from lesions that are above the foramen magnum. The jaw jerk reflex is referred to as the master reflex. It involves the mandibular branch of the trigeminal nerve as both its afferent and efferent arms.
