  1. Functions of the skeletal system
    • Provides structural support for whole body
    • Stores Minerals
    • Produces red blood cells, white blood cells, and platelets in the marrow
    • Protects delicate organs
    • Provides leverage for movement
  2. Classifications of bone shape:
    • Flat Bones
    • Sutural Bones
    • Long Bones
    • Irregular Bones
    • Sesamoid Bones
    • Short Bones
  3. Flat Bone
    Thin and flat bones of the skull, ribs, sternum, and scapulae
  4. Sutural Bones (wormian)
    Small flat irregular bones that appear in sutures of the skull
  5. Long Bones
    • Long bones of the:
    • Legs
    • Arms
    • Fingers
    • Toes
    • Hands
  6. Irregular Bones
    • Bones with complex shape like:
    • vertebrae
    • Ethmoid
    • Pelvic bones
  7. Sesamoid Bone:
    Form the patella
  8. Short Bones:
    • Carpal Bones
    • Tarsal Bones (ankle)
  9. Tubercle
    Small rounded projection from a bone
  10. Sulcus
    A deep narrow groove on a bone
  11. Diaphysis
    the shaft of a bone
  12. Condyle
    a smooth rounded articular process. (where two bones meet and articulate
  13. Trochlea
    A smooth grooved articular process. Shaped like a pulley
  14. Tuberosity
    • a small and rough projection on a broad area of a bone.
    • Where tendons connect
  15. Facet
    A flat articular surface
  16. Ramus
    Extension of a bone that makes an angle with the rest of the structure
  17. Fossa
    Shallow Depression or recess in the surface of a bone
  18. Crest
    a prominent ridge
  19. Epiphysis
    Each end of a long bone
  20. Metaphysis
    The midpoint between the shaft of a bone and the epiphysis
  21. Osteocyte
    Mature bone cells that maintain their surrounding matrix
  22. Osteoblasts
    Produce new bone matrix
  23. Osteoprogenitor
    Mesenchimal (stem cells) important in the repair of bone injuries
  24. Osteoclasts
    disolve matrix and release minerals
  25. appositional growth
    where the bone increases in diameter as it grows
  26. Periostium
    tissue that lines the outer surface of bones, has a fibrous and cellular layer
  27. endosteum
    a cellular lining to the medullary cavity of bones
  28. endochondral ossification
    the process of cartilage becoming bone. the cartilage allows bones to grow during infancy and adolescence.
  29. Calcitrol
    stimulates calcium reabsorption
  30. parathyroid gland embeded in the thyroid (neck)
    secretes parathyroid hormones that cause the body to increase calcium levels in the blood
  31. Calcitonin
    • is secreted when calcium levels are too high. Cause kidneys to flush calcium
    • Causes intestines to absorb less calcium
    • Slows osteoclasts while leaving osteoblasts alone
  32. how many bones are in the body
    roughly 206
  33. auditory ossicles
    • three in each inner ear
    • conduct vibrations produced by sound waves
  34. how many bones are in the appendicular skeleton
  35. How many bones are in the axial skeleton
  36. bones of the pelvic girdle
    • the paired coxal bones:
    • fused ilium, ischium, and pubis
  37. acetabulum
    socket that articulates with the femur
  38. glenoid cavity
    articulates with the humorous
  39. synarthosis
    strong joints with no movement
  40. Amphiarthrosis
    permits more movement than synarthrosis, but much stronger than free moving joint.
  41. diarthrosis
    freely moving joint
