The jaw jerk reflex can be classified as a dynamic stretch reflex. As with most other reflexes, the response to the stimulus is monosynaptic, with sensory neurons of the trigeminal mesencephalic nucleus sending axons to the trigeminal motor nucleus, which in turn innervates the masseter.
U.S. National Library of Medicine(0.00 / 0 votes)Rate this definition: Cumulative Trauma Disorders. Harmful and painful condition caused by overuse or overexertion of some part of the musculoskeletal system, often resulting from work-related physical activities. It is characterized by inflammation, pain, or dysfunction of the involved joints, bones, ligaments, and nerves.
Cumulative PTSD can be even more dangerous than PTSD caused from a single traumatic event, largely because cumulative PTSD is more likely to go unnoticed and untreated. When a catastrophic event occurs, such as an officer-involved shooting, most departments have policies and professionals to help an officer address and deal with the aftermath of an event.
