  20. fossa
    shallow cavity in a bone
  21. haversian canals
    minute spaces filled with blood vessels; found in compact bone
  22. malleolus
    round process on both sides of the ankle joint. The lateral malleolus is part of the fibula, and the medical malleolus is part of the tibia
  23. manubrium
    upper portion of the sternum; articulatees with the medial aspect of the clavicle
  24. mastoid process
    round projection on the temporal bone behind the ear
  25. medullary cavity
    central, hollowed-out area in the shaft of a long bone
  26. metaphysis
    flared portion of a long bone, between the diaphysis (shaft) and the epiphyseal plate (in this term, meta-means between)
  27. olecranon
    large process on the proximal end of the ulna; the point of the flexed elbow
  28. osseous tissue
    bone tissue
  29. ossification
    process of bone formation
  30. osteoblast
    bone cell that helps form bony tissue
  31. osteoclast
    bone cell that aborbs and removes unwanted bony tissue
  32. periosteum
    membrane surrounding bones; rich in blood vessels and nerve tissue
  33. phosphorus
    mineral substance found in bones in combination with calcium
  34. pubic symphysis
    are of confluence (coming together) of the two pubic bones in the pelvis. They are joined (sym-=together, -physis=to grow) by a fibrocartilaginous disk
  35. red bone marrow
    found in cancellous bone; site of hematopoiesis
  36. ribs
    twelve pairs of curved bones that form the chest wall. True ribs are the first 7 pairs; false ribs are pairs 8 to 10; floatingribs are pairs 11 and 12
  37. sella turcica
    depression in the sphenoid bone where the pituitary gland is located
  38. sinus
    hollow air cavity within a bone
  39. styloid process
    pole-like process extending downward from the temporal bone on each side of the skull
  40. suture
    immovable joint between bones, such as the skull (cranium)
  41. temporomandibular joint
    connection on either side of the head between the temporal bone of the skull and mandibular bone of the jaw
