TRANSCRIPT

Page 1: Chapter 8 - Articulations of Scapula

Sternoclavicular, Acromioclavicular, Coracoclavicular

Abduction (Protraction)Forward movement away the midline of the body; moving the scapula away from the spine during prostration of the shoulder girdle.

Serratus anterior Pectoralis minor Levator scapulae Pectoralis major (sternal head)

Adduction (Retraction)Backward movement toward the midline of the body; moving the scapula back toward the spine during retraction of the shoulder girdle.

Trapezius (middle fibers) Trapezius (lower fibers) Rhomboids Latissimus dorsi

DepressionInferior movement of the shoulder girdle; moving the scapula down.

Pectoralis minor Latissimus dorsi Pectoralis major Trapezius (lower fibers)

ElevationSuperior movement of the shoulder girdle; moving the scapula up.

Trapezius (upper fibers) Trapezius (middle fibers) Levator scapulae Serratus anterior (upper fibers)

Upward Rotation (Superior Rotation)Rotary movement of the scapula; moving inferior angle of scapula laterally and upward.

Trapezius (middle fibers) Trapezius (lower fibers) Serratus anterior (lower fibers)

Downward Rotation (Inferior Rotation)Rotary movement of the scapula; moving inferior angle of scapula medially and downward.
