Pectoralis major
adducts the arm and flexes the shoulder, forms the upper chest
medially rotates and adducts the arm (Also known as swimmers muscle)
stabilize the shoulder joint by holding the head of the humerus in the glenoid cavity during arm movements
muscle attaches the humerus to the scapula and clavicle and is the major abductor of the upper limb

medially rotates and adducts the arm (Also known as swimmers muscle)
stabilize the shoulder joint by holding the head of the humerus in the glenoid cavity during arm movements
muscle attaches the humerus to the scapula and clavicle and is the major abductor of the upper limb
