Chapter8 appendicularskeletonmarieb

  1. 1. Chapter 8, Bones, Part 2: The Appendicular Skeleton Appendicular Skeleton = Everything that is not the Axial Skeleton, i.e., pelvis and limbs Goal: Learn and locate the bones and markings of the appendicular skeleton
  2. 2. The Girdles <ul><li>Pectoral Girdle </li></ul><ul><ul><li>Supports the Arms </li></ul></ul><ul><ul><li>Clavicle and Scapula </li></ul></ul><ul><li>Pelvic Girdle </li></ul><ul><ul><li>Supports the Legs </li></ul></ul><ul><ul><li>Pelvis </li></ul></ul><ul><ul><ul><li>Ilium, ischium, pubic bone </li></ul></ul></ul>
  3. 3. Clavicle (collarbone) Manubrium to Acromion Frequently fractured
  4. 4. Scapula (shoulder blade) <ul><li>Glenoid </li></ul><ul><li>Spine </li></ul><ul><li>Acromion </li></ul><ul><li>Acromioclavicular joint </li></ul><ul><li>Inferior and Superior Angles </li></ul><ul><li>Origin of biceps brachii muscle: </li></ul><ul><ul><li>Coracoid Process </li></ul></ul><ul><ul><li>Supraglenoid tubercle </li></ul></ul>
  5. 5. The Arm <ul><li>Synonym: Upper limb </li></ul><ul><ul><li>Upper Arm = Brachium </li></ul></ul><ul><ul><li>Forearm = Antebrachium </li></ul></ul><ul><li>Humerus, Radius and Ulna </li></ul><ul><li>Carpus (wrist) </li></ul><ul><li>Hand (manus) </li></ul>
  6. 6. Humerus <ul><li>Head </li></ul><ul><li>Greater and Lesser Tubercles </li></ul><ul><li>Intertubercular Sulcus </li></ul><ul><ul><li>Biceps tendon </li></ul></ul><ul><li>Coronoid Fossa </li></ul><ul><li>Olecranon Fossa </li></ul><ul><li>Trochlea </li></ul><ul><li>Medial and Lateral Epicondyles </li></ul>
  7. 7. Radius Ulna <ul><li>Head, neck, shaft </li></ul><ul><li>Insertion of biceps brachii: </li></ul><ul><ul><li>Radial Tuberosity </li></ul></ul><ul><li>Radial Styloid Process </li></ul><ul><li>Olecranon </li></ul><ul><li>Trochlear notch </li></ul><ul><li>Coronoid Process </li></ul><ul><li>Ulnar Styloid Process </li></ul>Interosseous Membrane (between radius and ulna) Note how the two bones can cross “ Funny bone”
  8. 8. Carpus = Wrist <ul><li>Four Proximal </li></ul><ul><ul><li>Scaphoid, lunate, triquetrum, pisiform </li></ul></ul><ul><li>Four Distal </li></ul><ul><ul><li>Trapezium, trapezoid, capitate, hamate </li></ul></ul>Scaphoid is frequently fractured
  9. 9. Hand = Manus <ul><li>Five metacarpal bones (1-5) </li></ul><ul><li>Five fingers </li></ul><ul><ul><li>Labeled 1-5 </li></ul></ul><ul><ul><li>Thumb = Pollex = digit 1 </li></ul></ul><ul><ul><ul><li>Two phalangeal bones </li></ul></ul></ul><ul><ul><li>Fingers = phalanges = digits 2-5 </li></ul></ul><ul><ul><ul><li>Three phalangeal bones </li></ul></ul></ul><ul><ul><ul><ul><li>Proximal, middle, distal </li></ul></ul></ul></ul>
  10. 10. The Girdles <ul><li>Pectoral Girdle </li></ul><ul><ul><li>Supports the Arms </li></ul></ul><ul><ul><li>Clavicle and Scapula </li></ul></ul><ul><li>Pelvic Girdle </li></ul><ul><ul><li>Supports the Legs </li></ul></ul><ul><ul><li>Pelvis (os coxae) </li></ul></ul>
