    • Triceps Brachii – Long head
    • Proximal Attachment: Infraglenoid tubercle of scapula
    • Distal Attachment: posterior olecranon process of ulna
    • Action: extends the forearm at elbow (also extends the arm at the shoulder)
    • Biceps Brachii
    • Proximal Attachment:
    • Long head:supraglenoid tubercle of scapula
    • short head: coracoids process of scapula
    • Distal Attachment: radial tuberosity and bicipital aponeurosis to fascia of forearm
    • Action: both heads: weakly flex arm at shoulder (also flex forearm and Supinate forearm at elbow
    • Serratus anterior
    • Proximal Attachment: anterior surfaces of the first 8 or 9 ribs
    • Distal Attachment: anterior surface of medial border of scapula
    • Action: abducts scapula and upwardly rotates it while abducting the arm; stabilizes scapula by holding it to chest wall
    • Subscapularis
    • Origin: Subscapular fossa of scapula
    • Insertion: Lesser tuberosity of humerus
    • Action: Medially rotates arm and adducts it; helps to hold humeral head in glenoid cavity of scapula
    • Innervation: Upper and lower subscapular nerves (C5, C6 and C7) (C5, C6, C7)
  1. Name the articulations of the shoulder
    • Acromioclavicular Joint (AC)
    • Sternoclavicular Joint (SC)
    • Glenohumeral ( Shoulder ) Joint (GH)
  2. Supinator
    • Proximal Attachment:Lateral epicondyle of humerus
    • Distal attachment: Radial shaft
    • Action: supinates forearm
    • Nerve: radial
  3. Anconeus
    • Proximal Attachment: Lateral Epicondyle of the humerus
    • Distal attachment:later olecanon of unla
    • Action: assits with elbow extension
    • Nerve: radial
  4. Pronator teres
    • Proximal Attachment: medial epicondyle of humerus
    • Distal attachment:middle lateral surface of radius
    • Action:pronation of the forearm
    • Nerve:median
  5. List the range of motion of the wrist?
    extension/flexion, radial/ulnar
  6. Name the rotator cuff muscles?
    • Teres minor
    • Infraspinatus
    • Supraspinatus
    • Subscapularis
  7. List the range of motion of the thumb?
    • Palmar adduction/abduction
    • radial adduction/abduction
    • hyperextension/flexion
  8. Explain the functions of the scapular muscles?
    • Elevation, Depression, Protraction (abduction) Retraction (adduction)
    • Upward (lateral) rotation, Downward (medial) rotation, Anterior Tipping,
    • and Posterior Tipping
  9. Explain scapulothoracic (scapulohumeral) rhythm?
    The motions of the scapula, clavicle, and humorous working together to achieve full elevation of the arm. Scapulohumeral rhythm helps to achieve further range of movement. The Scapulohumeral rhythm is the movement of the scapula across the thoracic cage in relation to the humerus.
  10. Name the wrist flexor group?
    • palmaris longus
    • flexor digitorum superficialis
    • flexor carpi radialis
    • flexor carpi ulnaris.
  11. List the range of motion of the shoulder?
    • Abduction: 150 degrees
    • Forward flexion: 180 degrees
    • Extension: 45-60 degrees
    • Rotation - External Rotation: 90 degrees
    • Internal rotation: 70-90 degrees
  12. Name the articulations of the elbow?
    Flexion and extension
  13. Name the articulations of the wrist and hand?
    • Flexion
    • extension/hyperextension
    • adduction (ulna deviation)
    • abduction (radial deviation).
  14. Anterior Deltoid
    • Proximal Attachment:Lateral third of clavicle
    • Distal attachment: Deltoid tuberosity of humerus

    • Action: Pronation of forearm
    • Nerve: Median
  18. Shoulder Complex
    • Connects (via clavicle and scapula) the upper limb to the trunk; therefore, its articulations are included with those of the upper limb
    • Joints of the pectoral girdle (aside from aforementioned glenohumeral joint)
    • Proximal clavicle articulates with sternum and cartilage of 1st rib
    • Capsule thickened by anterior & posterior  SC ligaments
