2.  Origin  Insertion  Action  Nerve Supply  Anterior surface of scapula  Greater tubercle of humerus  Abducts the arm  Suprascapular nerve

4. -The supraspinatus is the muscle that runs along the top of the shoulder. -The distal supraspinatus tendon connects the supraspinatus to the upper arm bone, or humerus, and forms part of the rotator cuff, a group of muscles and tendons that support the shoulder. -The other three muscles whose connections to the arm constitute the rotator cuff are the subscapularis, which controls internal rotation; the teres minor, which controls external rotation; and the infraspinatus, which assists the arm in elevating during external rotation. -Supraspinatus muscle stabilizes the head of the arm bone in the shoulder joint preventing it from slipping upwards during shoulder movements.

5.  Origin  Insertion  Action  Nerve Supply  Tubercle below glenoid cavity and lateral an medial surfaces of humerus  Olecranon process of ulna  Extends elbow  Radial nerve

7. -They are named as triceps group of muscles, because it is not a single muscle. -These muscles make up over two thirds of your upper arm and work with the biceps muscles. -Triceps means three heads and that each of these heads (long, lateral and medial) performs a different function - -Anything that requires you to use straight arms generally means you are using your triceps. -The most common triceps injury is a pull or rupture, this can occur during overexertion in sports or weight lifting.

8.  Origin  Insertion  Action  Nerve Supply  Acromion Process, spine of the scapula, the clavicle  Deltoid tuberosity of humerus  Abducts, extends, and flexes arm  Axillary Nerve

10. -The deltoid is broken up into three parts the front deltoid, the side deltoid, and the posterior -Deltoids are one of the hardest muscles to develop while working out. -Constantly being involved in upper body movement the deltoid hardly gets and rest. -The name deltoid was originally called the Deltoideus. This name came about by the shape of the Greek letter Delta which is a triangle.
