muscles of the shoulder
Muscles of the shoulder
  • Deltoid
  • Pectoralis Major
  • Biceps Brachii
  • Rotator Cuff
    • Supraspinatus
    • Infraspinatus
    • Subscapularis
    • Teres Major
deltoid
Deltoid
  • Origin: Lateral 1/3 of the clavicle; acromion and spine of scapula
  • Insertion: Deltoid tuberosity of humerus
  • Action: Prime mover of arm abduction; some flexion and extension of shoulder
pectoralis major
Pectoralis Major
  • Origin: clavicle, sternum and cartilage of first 6 ribs
  • Insertion: Fibers insert by short tendon into greater tubercle of humerus
  • Action: Prime mover of arm flexion; adducts, medially rotates arm
biceps brachii
Biceps Brachii
  • Origin: Coracoid Process of scapula
  • Insertion: Proximal radius
  • Action: Flexes elbow, supinates forearm, weak shoulder flexor
rotator cuff
Rotator Cuff
  • Origin: Scapula
  • Insertion: Head of the humerus
  • Action: Abduction, internal rotation, external rotation
injuries of the shoulder
Injuries of the Shoulder
  • Biceps Tondonitis
  • Shoulder Impingement
biceps tendonitis
Biceps Tendonitis
  • Overuse of the biceps
    • Opposite of overuse?
  • 2 origins of the bicep
    • Coracoid process
    • Glenoid tubercle
  • Very common in swimmers, pitchers
shoulder impingement
Shoulder impingement
  • Commonly, an overuse injury
  • Muscles inflame in the shoulder and not enough space is allowed for muscles to swell
    • Compress the nerve
  • Sometimes it is a structural abnormality
    • Acromion Process hooks downward to close space
