    Study Notes

    Movements of Shoulder Girdle

    • Elevation of the scapula (Elevation of the Shoulder)
      • Muscles: Upper fibers of Trapezius, Levator scapulae
      • Nerve Supply: Cranial Accessory (11th), Dorsal Scapular nerve
    • Depression of the scapula (Depression of the Shoulder)
      • Muscles: Upper fibers of Trapezius, Pectoralis minor
      • Nerve Supply: Cranial Accessory (11th), Medial Pectoral Nerve
    • Upward rotation of the scapula (Abduction, Raising the arm above the head)
      • Muscles: Upper fibers of Trapezius, Lower fibers of Trapezius, Lower digitations of serratus anterior
      • Nerve Supply: Cranial Accessory (11th), Long Thoracic Nerve
      • Effect of Lesion: Winging of Scapula
    • Downward rotation of the scapula
      • Muscles: Levator scapulae, Rhomboideus major and minor, Pectoralis minor
      • Nerve Supply: Dorsal Scapular nerve, Medial Pectoral Nerve
    • Protraction (Movement of the shoulder forward)
      • Muscles: Serratus anterior, Pectoralis minor
      • Nerve Supply: Long Thoracic Nerve, Medial Pectoral Nerve
    • Retraction (Movement of the shoulder backward)
      • Muscles: Middle fibers of trapezius, Rhomboideus major and minor
      • Nerve Supply: Cranial Accessory (11th), Dorsal Scapular nerve

    Actions of Trapezius

    • Elevates scapula, rotates scapula upward, adducts scapula (draws scapula toward the vertebral column), depresses scapula

    Actions of Levator Scapulae

    • Elevates the Scapula

    Actions of Rhomboidei

    • Retract and stabilize the scapula, rotate it downward

    Actions of Serratus Anterior

    • Protracts and rotates the scapula upward, stabilizes the scapula against the chest wall, assists in breathing

    Actions of Pectoralis Major

    • Adducts, flexes, medially rotates the arm at the shoulder joint, assists in respiration, draws arm across the chest, depresses the shoulder

    Actions of Subscapularis

    • Medially rotates the arm at the shoulder joint, helps to stabilize the shoulder joint, prevents lateral rotation, pulls the arm into the body

    Actions of Latissimus Dorsi

    • Extends, adducts, and medially rotates the arm at the shoulder joint, pulls the arm downward and backward

    Actions of Deltoid

    • Abducts (middle fibers), Flexes and medially rotates (anterior fibers), Extends and laterally rotates (posterior fibers) the arm at the shoulder joint
      • Effect of Lesion: Flat Shoulder

    Actions of Supraspinatus

    • Abducts the arm at the shoulder joint, helps to stabilize the shoulder joint
      • Effect of Lesion: Flat Shoulder

    Actions of Infraspinatus

    • Laterally rotates the arm at the shoulder joint, helps to stabilize the shoulder joint

    Actions of Teres Minor

    • Laterally rotates the arm at the shoulder joint, helps to stabilize the shoulder joint

    Movements of Wrist Joint

    • Flexion
      • Muscles: Flexor carpi radialis, Flexor carpi ulnaris, Palmaris longus, Flexor digitorum superficialis, Flexor digitorum profundus, Flexor pollicis longus
      • Assisted by: Extensor digitorum, Extensor carpi radialis longus, Extensor indicis
    • Extension
      • Muscles: Extensor carpi radialis longus, Extensor carpi radialis brevis, Extensor digiti minimi, Extensor carpi ulnaris, Extensor pollicis longus
      • Assisted by: Flexor carpi ulnaris, Flexor carpi radialis
    • Adduction
      • Muscles: Flexor carpi ulnaris, Extensor carpi ulnaris
    • Abduction
      • Muscles: Extensor carpi radialis longus and brevis, Flexor carpi radialis
      • Assisted by: Abductor pollicis longus, Extensor pollicis longus and brevis

    Movements of 1st Carpo-Metacarpal (CMJ) & Metacarpo-phalangeal (MCPJ) Joints

    • Flexion (MCPJ)
      • Muscles: Flexor pollicis brevis and longus, Opponens pollicis
    • Extension (MCPJ)
      • Muscles: Extensor pollicis longus, Extensor pollicis brevis
    • Adduction (CMJ)
      • Muscles: Adductor pollicis, 1st palmar interossoeus
    • Abduction (CMJ)
      • Muscles: Abductor pollicis longus, Abductor pollicis brevis
    • Opposition (medial rotation of thumb)
      • Muscles: Opponens pollicis
