Anatomy Section 7

  1. Bones of the Schoulder Girdle
    Scapula, clavicle and sternum
  2. Clavicle 
    • Last bone to ossify (21 years)
    • attaches to sternum and Scapula
    • Transmits shocks from upper limb to the axial skeleton
    • medial 2/3 or convex anteriorly 
  3. how does clavical differ from other long bones
    • ossifies with cartilage 
    • no marrow cavity
    • no medullary cavity 
    • spongy bone shell of compact bone`
  4. ligaments attached to Clavical
    • sternoclavicular
    • interclavicular
    • costoclavicular
    • coracoclavicular
    • acromioclavicular
  5. Muscles attached to Clavical
    • Deltoid
    • trapezius
    • pectoralis major
    • sternocleidomastoid
    • subclavius
  6. fracturing of clavical
    • common site is junction between two curves 
    • lateral fragment displaced downward
    • subclavian vien and artery can lie close in relation to fracture site and be damaged 
  7. Cleidocranial dysostosis
    • condition in which clavicals are congenitally absent , or imperfectly developed.
    • shoulder droop, and can be approximated anteriorly in front of chest 
  8. Scapula
    • between 2nd and 7th rib
    • triangular flat bone 
  9. Articulations of Scapula
    • Acromioclavicular (AC)
    • Coracoclavicular
    • Glenohumeral (shoulder)
  10. Ligaments attached to Scapula
    • Acromioclavicular
    • Coracoclavicular
    • glenohumeral
    • superior transverse scapular
    • spinoglenoid (inferior transverse scapular)
    • Costocoracoid (part of the clavipectoral fascia)
  11. Scapula Bursae
    • subscapular- communicates with shoulder joint
    • subacromial- communicate with subdeltoid bursa
  12. Glenoidal Labrum 
    a fibrocartilaginous rim attached around the margin of the glenoid cavity. it deepends the articular cavity, and protects the edge of the bone
  13. winged Scapula
    •  scapula sticks out back
    • caused by damage to the long thoracic nerve by weakness in in the serratus anterior muscle 
  14. Bones thsat make up upper limb
    • Humerus
    • Ulna
    • Radius
    • Carpal
    • Metacarpals
    • Phalanges
  15. Parts of the Humerus
    • Upper (Proxmal) end
    • Shaft
    • Lower (distal) end
  16. Anatomical Neck
    • slight constriction at margin of articular surface and head
    • attaches to capsular ligament of shoulder
  17. Surgical Neck
    • it is constricted at the upper end of shaft just below tubercles
    • common site of fracture
    • axillary nerve and Posterior Circumflex Humeral Artery lies medial 
  18. intertubercular sulcus contains
    • Long head of the biceps tendon
    • synovial sheath of bicep
    • Ascending branch od anterior circumflex humeral artery
  19. Muscles attached to greater tuberosity
    • supraspinatus
    • infraspinatus
    • teres minor
    • transverse ligament 
  20. Muscles attached to lesser tubercle
    • subscapularis
    • transverse ligament 
  21. Muscles in Intertubercular Sulcus
    • Pectoralis Major
    • Teres major
    • Latissimus dorsi
  22. Muscle attachments to the anterior surface of Humerous
    • Caracobrachialis 
    • Deltoid
    • Brachialis 
  23. Attachment to the posterior surface
    • Lateral head of triceps brachii
    • Medial head of triceps brachii
    • long head of triceps brachii
  24. Surgical Neck fracture (clinical)
    Axiallary Nerve
  25. Middle shaft fracture (clinical)
    radial nerve (saturday Night[cruthch] palsy)
  26. Supracondyla (distal) fracture (clinical)
    Median Nerve
  27. Medial epicondyle (clinical)
    Ulnar nerve
  28. Avulsion fracture fo greater tubercle of humerus (clinical)
    Medial rotation
  29. Neurovascular Bundles that associate with the upper limb
    • Axillary nerve / posterior circumflexhumeral artery
    • Radial Nerve & profunda brachii
    • Median Nerve and brachial artery
    • ulnar nerve and superior ulnar collateral artery 
    • Musculocutanous
  30. 3 parts of shoulder joint
    • clavical
    • scapula
    • humerous
  31. what joints facilitate shoulder movement
    • Acromioclavicular (AC) Joint
    • glenohumeral (shoulder) Joint 
  32. what structure keeps the ball and socket joint together, provides mobility, and strength
    rotator cuff
  33. 2 slimy sac-like structures that help provide smooth gliding between bone, muscle, and tendon
  34. why is the shoulder subject to easy injury?
    ball is too large for socket
