There are a number of other joints in the region which all move in unison in order to generate a stable movement. The action, or particular movement of a muscle, can be described relative to the joint or the body part moved. They also contribute to deep inhalation. View Origin and Insertion points as a layer map Origin and Insertion points are available as a layer of the Skeletal System, which show a map of all attachment points across the full skeleton. Insertion: greater trochanter on the back of the femur The sternocleidomastoid divides the neck into anterior and posterior triangles. Posterior dislocation can occur in epileptics or electric shocks. S: supraspinatus I: infraspinatus T: teres minor S: subscapularis With 'SITS', recalling this order also helps remember the insertions of these muscles, with the order being superior, middle, and inferior facets of the greater tubercle of the humerus for supraspinatus, infraspinatus and teres minor respectively and .

The forearm is the region between the elbow and thewrist and is composed of an extensor and flexor compartment. The genioglossus (genio = chin) originates on the mandible and allows the tongue to move downward and forward. For example, that same muscle, the biceps brachii, performs flexion at the elbow, in which the elbow is the joint. Due to these attachments, the triceps is stretched during forearm flexing. Registered Nurse, Free Care Plans, Free NCLEX Review, Nurse Salary, and much more. Muscles always pull. A FOSH may fracture the bone. The extrinsic muscles of the hand originate outside the hand, commonly the forearm, and insert into hand structures. It is also capable of weakly supinating and pronating the forearm. Forearm muscle origins on humerus: Supinator, Medial Tricep, Lateral Tricep, Pronator, Brachialis. It causes extension of the IP joints, the MP joints, and wrist. The extrinsic muscles move the whole tongue in different directions, whereas the intrinsic muscles allow the tongue to change its shape (such as, curling the tongue in a loop or flattening it). Find it on your own body if you can. psoas major - origin : lumbar vertebrae It also has a role in stabilizing the humerus and part of the rotator cuff of four muscles. Reading time: about 1 hour.
