Anterior Muscles § Pectoralis Minor § Serratus Anterior
Pectoralis Minor § Origin: Anterior surface of 3, 4, and 5 ribs § Insertion: Coracoid process § Actions: § Abduction of the scapula § Downward rotation of the scapula § Depression of the scapula
Serratus Anterior § Origin: Lateral surface of upper 8 ribs § Insertion: Anterior surface of medial border and inferior angle of scapula. § Actions: § Abduction of the scapula § Upward Rotation of the scapula
Posterior Muscles § Levator Scapluae § Trapezius § Rhomboid
Levator Scapulae § Origin: Transverse processes of the first 4 cervical vertebrae. § Insertion: Superior angle and medial border of the scapula. § Actions: Elevation of the scapula
Trapezius § Origin: Occipital bone, ligamentum nuchae, spinous process of the C 7 and all Thorasic vertebrae § Insertion: § 1. Lateral 1/3 of clavicle. § 2. Top of Acromion process. § 3. Upper border of spine of the scapula. § 4. Medial surface of spine of the scapula. § Actions: § Upper – elevation of the scapula § Middle – elevation, upward rotation, & adduction of the scapula § Lower – depression, AC adduction and upward rotation of the scapula
n Upper – elevation n Middle – elevation, upward rotation, & adduction n Lower – depression, adduction and upward rotation
Pull of the lower fibers Movement of scapula
Rhomboid (major and minor) § Origin: Ligamentum nuchea and spinous process of C 1 -7 and 2 -5 T § Insertion: Medial border of the scapula § Actions: § Adduction of the scapula § Downward rotation of the scapula § Elevation of the scapula
Subclavius § Origin: Superior aspect of first rib § Insertion: Inferior aspect at mid-clavicle § Action § Depression of the scapula § Stabilization of the scapula
