Hi guys, i am moving to a new address that's served by optimum online. For TV, i want to get the cheapest package (just basic channels + their HD counterparts).
The prime mover for flexion of the shoulder muscles used are the following: 1  Pectoralis Major Clavicle. 2  Anterior Deltoid. 3  Biceps Brachii Short Head. 4  Coracobrachialis.
A shoulder flexion or extension refers to how the shoulder moves the arms either out in front or behind you. Loss of this range of motion can limit activities and may need work with a physical therapy.
