It moves the scapula and supports the arm. The trapezius has three functional parts: an upper (descending) part which supports the weight ...
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. This reflex is used to judge the integrity of the upper ...

[3] various sports injuries, typically occurring from a blow to the ribs underneath an outstretched arm. surgery for shoulder and thorax. [8]
