  1. Functions of the Skeletal System
    • Provides frame and strength to the body
    • Produces body movement
    • Provides protection for organs
    • Serves as a storehouse for calcium salts
    • Produces blood cells in the bone marrow
  2. bone
    hard connective tissue impregnated with calcium substance (206 bones in the adult skeleton)
  3. cartilage
    firm connective tissue found primarily in joints, thorax walls, larynx, ariway passages, and ears
  4. ligaments
    bands of fibrous tissue that connect the articulating ends of bones to facilitate or limit movement; do not confuse ligaments with tendons, which connect muscle to bone
  5. Joints
    areas where two or more bones come together or articulate, such as the knee, shoulder, and neck
  6. Abduction
    moving away from the body midline
  7. Adduction
    moving toward the body midline
  8. Circumduction
    drawing an imaginary circle with a body structure
  9. Eversion
    turning wrists or ankles outward, away from the body
  10. extension
    bringing the limbs or phalanges toward a straight postition (the opposite of flexion) such as opening the fingers if a closed hand
  11. Flexion
    bending (the opposite of extension), such as closing the fingers of the hand
  12. Hyperextension
    extreme or abnormal extension, usually resulting in injury
  13. Inversion
    turning inside out (the opposite of eversion), such as turning the heels outso toes face each other
  14. Plantar flexion
    pointing toes downward, which flexes the arch of the foot
  15. Rotation
    turning on axis, such as turning the head to indicate "No"
  16. axial skeleton

  33. Thoracic vertebrae
    (12 vertebrae) chest (mid back)attached to the posterior portion of ribs
  34. Lumbar Vertebrae

  36. Coccyx
    tail bone
  37. Ribs
    12 pair of bones that make up the thorax; the bars of the cage
  38. Sternum
    breast bone that, with the ribs, protects the heart
  39. Manubrium
    top of the breast bone that joins with the clavicle and first ribs
  40. xiphoid process
    small tip at the lower end of the sternum
  41. Appendicular skeleton
    consists of the bones of the upper and lower ectremities and the girdles attaching them to the axial skeleton portion
  42. clavicle
    collar bone which joins the sternum at the anterior and the scapula laterally
  43. Scapula

  48. metacarpals
    the five bones of the palm of the hand
  49. phalanges
    fingers (three bones each) and thumbs (two bones each)
  50. Ilium
    superior wing-shaped portions of hip bones
  51. Ischium
    inferior portion of hip bones that supports weight when sitting
  52. Pubis
    anterior union of the hip bones
  53. Femur
    thigh bone; the body's largest, longest, strongest bone
  54. patella
    knee cap
  55. tibia
    shin bone
  56. fibula
    smaller leg bone,lateral to the tibia
  57. tarsals
    the seven ankle and foot bones (largest is the calcaneous, or heel bone)
  58. metatarsals
    the five foot bones
  59. phalanges
    toe bones (three bones each), great toes (two bones each)
  60. cleft palate
    congenital deformity caused by a malunion of the maxilla, leaving an opening in the roof of the mouth (palate)
  61. spina bifida
    congenital deformity caused by a malformation of vertebrae that exposes the spinal column
  62. scoliosis
    abnormal lateral curvature of the vertebral column
  63. kyphosis
