Human Skeleton (appendicular)
Show Answers:

  1. Scapula
    Shoulder Blade
  2. Glenoid cavity
    "shoulder socket"

    attaches directly to the head of the humerus
  3. Acromion
    the most upper bony process of the scalpula, extends laterally to the shoulder

    articulates with the clavicle
  4. coracoid process
    the anterior upper bony process of the scapula.

    together with the acromion, it stabilizes the shoulder joint.  it is apart of the deltoid and pectoralis major muscles
  5. Supraspinous fossa
    the posterior upper, smooth part of scapula

    it is the origin of the Supraspinatus
  6. infraspinous fossa
    the posterior, lower part of the scapula (major smooth surface area)

    it is the origin of the Infraspinatus
  7. subscapular fossa
    large surface area that is the DEEP posterior section of the scapula

    the origin of the subscapularis muscle
  8. Humerus head
    a dome-shaped structure that goes into the shoulder joint and has the articular capsule
  9. greater tubercles (humerus)
    the larger bump on the top of humerus (NOT THE HEAD)

    Gives insertion to the supraspinatus, infraspinatus and teres minor
  10. lesser tubercles
    on top of humerus and is the smallest bump

    insertion of the subscapularis
  11. intertubercular sulcus
    this is the groove between the greater and lesser tubercles.

    it is the insertion of the biceps brachii
  12. lateral epicondyle
    on the distal end of humerus, it is the lateral bump

    origin of the supinator
  13. medial epicondyle
    at the distal end of the humerus, it is medial and larger than the lateral epicondyle

    the ulnar nerve is protected by this... thus the "funny bone" 

    origin of the pronator teres
  14. capitulum
    distal end of humerus, it articulates with the head of the radius (so right facet of right arm)
  15. trochlea
    distal end of humerus, it articulates with the head of ulna (left articulation of right arm) 

    (part of elbow joint)
  16. Ulna
    from the anatomical position it is medial to the radius

    part of forearm (antebrachial)
  17. olecranon
    The actual "elbow bone" 

    proximal end of ulna
  18. trochlear notch
    proximal end of unla

    serves as the large depression for the trochlea of the humerus
  19. radial notch
    proximal end of ulna

    serves as the depression for the head of the radius
  20. styloid process (ulnar)
    bumpy distal end of ulnar

    provides articulation for carpal ligaments and muscles
  21. radius
    antebrachial, from the anatomical position it is lateral to the ulna
  22. radius head
    proximal end of radius

    articulates with the capitulum of humerus
  23. radial tuberosity
    a bump on the proximal end of the radius deep in the antebrachial region

    serves as an insertion for biceps brachii
  24. styloid process (radius)
    lateral bump at distal end of radius, is the insertion of the brachialradialis
  25. carpal (wrist)
    bones contained in the wrist
  26. Os coxae (ossa coxae is plural)
    the main and lateral parts of the hip bone
  27. acetabulum
    the concave surface of the pelvis where the head of the femur goes
  28. obturator foramen
    is the hole created by the ischium and pubis bones of the pelvis where nerves and blood vessels pass
  29. sacroiliac joint
    the joint between the sacrum and ilium of the pelvis
  30. ilium (pelvic)
    upper and largest bone of the pelvis. 

    it has the iliac crescent (top border)
  31. anterior superior iliac spine
    top front of the iliac bone

    provides attachment for the inguinal ligament, and the sartorius muscle
  32. pubis
    most anterior part of pelvis

    forms part of the acetabulum
  33. pubic symphysis
    the joint that unites the left and right pubic bones
  34. ischium
    most inferior part of pelvis
  35. ischial tuberosity
    most inferior part of ischium

    the part that you "sit with"
  36. head of femur
    most proximal part of femur, is the part that articulates with pelvis
  37. neck of femur
    a proximal part of femur that is the neck of the head

    most prominent in elderly
  38. greater trochanter
    larger bump on proximal end of femur that is NOT the head

    insertion of the gluteus medius
  39. lesser trochanter
    proximal end, the smallest bump
  40. medial condyle
    medial distal bump of the femur

    larger than lateral (more weight bearing)
  41. lateral condyle
    lateral distal bump of femur
  42. medial epicondyle (femur)
    the medial distal bump that is on the side of femur

    origin of the gastrocnemius
  43. lateral epicondyle (femur)
    smaller, distal and on the side of the femur

    attaches the fibular collateral ligament
  44. patella
    "knee cap"
  45. Tibia
    medial and more weight bearing bone of the leg (vs fibula)
  46. tibial tuberosity
    the anteriorly protruding part of tibia

    provides attachment to the patellar ligament
  47. medial malleolus
    the distal lateral bump of tibia
  48. fibula
    lateral and less weight bearing of the leg bones
  49. head of fibula
