    abnormal sensation (eg. burning, tingling, numbness)
  18. periosteum
    fibrous connective tissue covering bone
  19. remodeling
    process that ensures bone maintenance through stimultaneous bone resorption and formation
  20. resorption
    removal/ destruction of tissue, such as bone
  21. scoliosis

    membrane in joint that secretes lubricating fluid
  24. tendon
    cord of fibrous tissue connecting muscle to bone
  25. tone (tonus)
    normal tension (resistance to stretch) in resting muscle
  26. trabeculae
    latticelike bone structure; cancellous bone

  34. contracture
    abnormal shortening of muscle or joint, or both; fibrosis
  35. cortical bone
    compact bone
  36. crepitus
    grating or crackiling sound or sensation; may occur with movement of ends of a broken or irregular joint surface
  37. diaphysis
    shaft of long bone
