Jaw Jerk Reflex Test

Jaw Jerk Reflex Test - The jaw jerk reflex is referred to as the master reflex. This stretch reflex is used to test the status of a patient’s trigeminal nerve (cranial nerve v). The chief nucleus, located in the pons, receives information about light touch as well as proprioceptive information about the mandible, which are both relayed to the thalamus and, ultimately, to the postcentral gyrus of the parietal lobe. 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 examiner places a thumb on the patient's chin, after which the patient is instructed to relax the jaw completely with the mouth closed, and the examiner then taps the chin to elicit the jaw jerk reflex. The jaw jerk is exaggerated with bilateral lesions above the level of trigeminal nerve but will not be affected by lesions below it in the spinal cord. The jaw jerk reflex, or 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.
