  1. Radiographic Anatomy and Positioning of the Upper Extremity

  2. Intended Learning Outcomes • The student should be able to recognize clinical radiographic technical principles of the upper limb

  3. Upper extremity consists of: • Phalanges • Metacarpals • Carpals • Radius • Ulna • Humerus

  4. The hand & wrist consists of : • 27 Bones • Phalanges - 14 • Metacarpals - 5 • Carpals - 8
