The muscle inserts onto the anterior lateral surface of the body of the radius. Insertion: mastoid process of temporal bone, occipital bone. This is a fracture of the proximal third of the ulna with associated dislocation of the proximal radioulnar joint. These include the digastric muscle, which has anterior and posterior bellies that work to elevate the hyoid bone and larynx when one swallows; it also depresses the mandible. Rather, antagonist contraction controls the movement by slowing it down and making it smooth. It controls extension, lateral flexion, and rotation of the vertebral column, and maintains the lumbar curve. This muscle divides the neck into anterior and posterior triangles when viewed from the side (Figure 11.4.8). It is innervated by the posterior interosseous branch. This muscle also prevents the humeral head from moving too far upwards while the deltoidis in action, as do all the rotator cuff muscles. The origin is the fixed attachment, while the insertion moves with contraction. It is innervated by the axillary nerve. The geniohyoid depresses the mandible in addition to raising and pulling the hyoid bone anteriorly. The sternocleidomastoid divides the neck into anterior and posterior triangles. 1 / 24.
