Serratus anterior
The pectoralis major is a large chest muscle that is responsible for flexing, adducting, and internally rotating the arm at the shoulder joint. It also helps to stabilize the shoulder joint during movement.
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
The Serratus Anterior muscle is responsible for holding the scapula against the chest wall. It helps stabilize the scapula and is important for proper shoulder movement and function.
The serratus anterior muscle is located between the scapula and ribcage. It has a serrated ("saw-like") appearance and is responsible for stabilizing the scapula against the ribcage during arm movements.
Extensor. It will extend the neck and adduct the scapula.
The pectoralis minor originates on the third to the fifth ribs (and elevates ribs). It depresses the scapula (and elevates ribs).
stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula
The scapula is not a muscle; it is a bone.
The pectoralis major is a large chest muscle that is responsible for flexing, adducting, and internally rotating the arm at the shoulder joint. It also helps to stabilize the shoulder joint during movement.
Trapezius - it elevates and depresses the scapula.
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
The supraspinatus muscle originates from the supraspinous fossa of the scapula.
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Serratus Anterior, moves scapula forward.
Platysma
Trapezius muscle- located from the skull through the cervical and thoracic vertebrae to the lateral 1/3 of the clavicle and spine of scapula. Function: Elevates, Depresses, Retracts, and rotates the scapula up and down. Innervated by the Spinal Accessory Nerve
Abducts scapula (moves scapula away from spinal column)
