  • 9. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Upper Limbs  Humerus  Forms the arm  Single bone
  • 10. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Upper Limbs Figure 5.22a–b
  • 11. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Upper Limbs  The forearm has two bones  Ulna  Medial bone in anatomical position  Radius  Lateral bone in anatomical position

  • 13. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Upper Limbs  The hand  Carpals—wrist  Metacarpals—palm  Phalanges—fingers
  • 14. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Upper Limbs Figure 5.23
  • 15. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Pelvic Girdle  Formed by two coxal (ossa coxae) bones  Composed of three pairs of fused bones  Ilium  Ischium  Pubis
  • 16. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Bones of the Pelvic Girdle  The total weight of the upper body rests on the pelvis  It protects several organs  Reproductive organs  Urinary bladder  Part of the large intestine

  • 19. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Gender Differences of the Pelvis  The female inlet is larger and more circular  The female pelvis as a whole is shallower, and the bones are lighter and thinner  The female ilia flare more laterally  The female sacrum is shorter and less curved  The female ischial spines are shorter and farther apart; thus the outlet is larger  The female pubic arch is more rounded because the angle of the pubic arch is greater
