REQUIRED MATERIALS

SUMMARY OF REQUIRED ANATOMICAL STRUCTURES

Humerus 

  1. Head of Humerus - the large, round, smooth region on the proximal end of the bone; it articulates with the glenoid cavity of the scapula to form the glenohumeral (shoulder) joint.
  2. Capitulum - a knob-like structure located on the anterior surface of the distal humerus, lateral to the trochlea; articulates with the radius bone of the antebrachium
  3. Trochlea - a spindle- or pulley-shaped region (trochlea = “pulley”), which articulates with the ulna bone ; it is medial to the capitulum. 
  4. Olecranon Fossa - a larger depression on the posterior, distal aspect of the humerus; receives the olecranon process of the ulna when the forearm is fully extended.
  5. Greater Tubercle - a bony prominence located on the lateral side of the proximal humerus; serves as an attachment site for muscles that act across the shoulder joint.
  6. Lesser Tubercle - found on the anterior aspect of the proximal humerus; serves as an attachment site for muscles that act across the shoulder joint
  7. Deltoid Tuberosity - a roughened, V-shaped region located on the lateral side in the middle of the humerus shaft; site of attachment for the deltoid muscle.
  8. Coronoid Fossa - anterior, distal depression of the humerus superior to the trochlea; receives the coronoid process of the ulna
  9. Lateral Epicondyle - a large prominence found on the lateral side of the distal humerus.
  10. Medial Epicondyle - a large prominence found on the medial side of the distal humerus. 
  11. Radial Fossa - a depression on the anterior, distal aspect of the humerus superior to the capitulum; receives the head of the radius when the elbow is flexed.
  12. Lateral Supracondylar Ridge - a roughened ridge of bone superior to the lateral epicondyle
  13. Medial Supracondylar Ridge - a roughened ridge of bone superior to the medial epicondyle
  14. Intertubercular Groove - a shallow depression between the greater and lesser tubercles; also known as the bicipital groove because it provides passage for a tendon of the biceps brachii muscle

Radius

  1. Head of Radius - a disc-shaped structure that forms the proximal end
  2. Radial Tuberosity - an oval-shaped, bony protuberance on the medial side of the proximal radius that serves as a muscle attachment point 
  3. Styloid Process - a pointed projection on the lateral side of the distal radius
  4. Ulnar Notch - a shallow depression on the medial side of the distal radius; articulates with the ulna

Ulna 

  1. Olecranon Process - the proximal end of the ulna; forms the bony tip of the elbow.
  2. Coronoid Process - a prominent lip of bone that forms the inferior margin of the trochlear notch
  3. Trochlear Notch - the proximal end of the ulna; resembles a crescent wrench with its large, C-shaped trochlear notch. This region articulates with the trochlea of the humerus as part of the elbow joint.
  4. Ulnar Tuberosity - a roughened area on the anterior ulna; distal to the coronoid process of the ulna
  5. Styloid Process - a short bony projection on the posterior side of the distal ulna
  6. Radial Notch - a small, smooth area on the lateral side and slightly inferior to the trochlear notch; the site of articulation between the proximal radius and the ulna

Carpals - 8 bones forming the wrist; arranged in two rows

Metacarpals - 5 bones; they connect phalanges to carpal bones.

Phalanges - 14 bones; form fingers or digits
