By the end of this section, you will be able to: Identify the following muscles and give their origins, insertions, actions and innervations: The skeletal muscles are divided into axial (muscles of the trunk and head) and appendicular (muscles of the arms and legs) categories. Pronator teres muscle is the larger of the pronator muscles and has two heads. In anatomical terminology, chewing is called mastication. The Colles fracture is a fracture of the distal radius (within two centimetres of the wrist joint) with associated dorsal translocation of the distal fragment.

[3] Origin and Insertion The posterior muscles of the neck are primarily concerned with head movements, like extension. It is a powerful superficial muscle of the shoulder. A rotator cuff tear presents with general pain with overhead activities and may present with night pain. Semispinalis capitis: Origin: transverse processes of C7-T12. The long head arises from the supraglenoid tubercle of the scapula and passes through the intertubercular sulcus in its own synovial sheath. The biceps brachii is the agonist in forearm flexion.

Supraspinatus muscle:This rotator cuff muscle is deep and originates from the supraspinous fossa which is located on the posterior superior portion of the scapula. action: elevates scapula, The posterior hamstring muscle group - Those in the same compartment will have the same action. Some axial muscles cross over to the appendicular skeleton. This expression of trauma makes the hand appear to be dorsiflexed.
