  1. Head
  2. Greater tubercle
  3. Lesser tubercle
  4. Deltoid tuberosity
  5. Capitulum
  6. Trochlea
  7. Medial epicondyle
  8. Lateral epicondyle
  9. Coronoid fossa
  10. Olecranon fossa

Radius

• Bone Markings to Identify:
  1. Radial tuberosity
  2. Head and neck
  3. Styloid process

Ulna

• Bone Markings to Identify:
  1. Coronoid process
  2. Olecranon process
  3. Styloid process
  4. Trochlear notch

Bones of the Hand

• Bone Markings Learned Previously:
  1. Scaphoid
  2. Triquetrum
  3. Trapezium
  4. Capitate
  5. Lunate
  6. Pisiform
  7. Trapezoid
  8. Hamate
  9. Metacarpals (I-V)
  10. Phalanges (I-V)
      • 10.1 Distal phalanges
      • 10.2 Middle phalanges
      • 10.3 Proximal phalanges

Exercise 10: Bone Markings Significance

• Capitulum:
  • Definition: A condyle that forms a joint with the radius.
• Trochlea:
  • Definition: A condyle that forms a joint with the ulna.

Collaborative Learning

• Quiz:
  • Engage with peers regarding the bones and bone markings of the arm and hand.
• Practice:
  • Utilize whiteboards to enhance the practice of spelling bone names.

Review for Long Bones

• Focus Areas:
  • Review the bones and bone markings of the leg presented on day one.
  • Important to differentiate between left and right bones for long bones such as:
  • Humerus
  • Tibia
  • Femur
