  1. what connects the shoulder to the upper trunk:
    • clavicle
    • scapula
  2. spine of the scapula becomes continuous c/ the:
  3. humerus articulates c/ the:
    glenoid fossa of the scapula
  4. what is the ONLY osseous attachment holding the upper extremity to the trunk:
    sternoclavicular joint
  5. what shape is the scapula?
    curved to accommodate the chest wall
  6. on the lateral end, the acromion process articulates c/ the clavicle to form:
    acromioclavicular joint
  7. what makes the glenoid fossa wider and deeper to accommodate head of the humerus;
    the fibrocartilaginous Glenoid Labium
  8. attaches the coracoid process and acromion:
    very strong
    coracoacromial ligament
  9. what attaches clavicle to coracoid process:
    • the corcoclavicular ligament
    •    Trapezoid ligament (front)
    •    Conoid ligament (behind)
  10. attaches acromion and clavicle:
    very little movement
    acromioclavicular ligament
  11. which joint has the most movement?
    sternoclavicular joint
  12. what are the ligaments of the sternoclavicular ligaments?
    • interclavicular
    • costoclavicular
    • Ant/post sternoclavicular ligaments
  13. movements of the scapula:
    • elevation
    • depression
    • protraction
    • retraction
    • upward rotation
    • backward rotation
  14. scapula ROM:
    • scapula only provides 1/3 of total ROM
    • in order for your arm to raise up last 1/3, scapula must not be fixed
  15. structures on the proximal humerus:
    • head of the humerus
    • bicipital grove
    • greater tubercle
    • lesser tubercle
    • deltoid tuberosity
  16. what attaches to greater/lesser tubercle:
    rotator cuff muscles attach
  17. what attaches to the deltoid tuberosity:
  18. this joint capsule itself is a loose, weak structure that permits lots of movement:
    NOT for major support
    Glenohumeral joint
  19. movements of the glenohumeral joint:
    • flexion
    • extension
    • abduction
    • adduction
    • internal rotation
    • external rotation
  20. long head of the biceps muscle arises from:
    supraglenoid tubercle
  21. long head of the triceps muscle arises from:
    infraglenoid tubercle
  22. 4 short muscles of the shoulder and their attachments:
    • subscapularis (on front): lesser tubercle
    • supraspinatus (on back): greater tubercle
    • infraspinatus (on back): greater tubercle
    • Teres minor (on back): greater tubercle
  23. 4 tendons converge on the humerus to form a continuous cuff of flat supportive tendons called the rotator cuff - keeps head from popping out.
    what are the muscles from these 4 tendons?
    • subscapularis
    • supraspinatus
    • infraspinatus
    • teres minor
