  1. acetabulum
    rounded depression, or socket, in the pelvis that joins the femur (thigh bone), forming the hip joint
  2. acromion
    outward extension of the shoulder blade forming the point of the shoulder. It overlies the shoulder joint and articulates with the clavicle
  3. articular cartilage
    thin layer of cartilage covering the bone in the joint space
  4. bone
    dense, hard connective tissue composing the skeleton. Ex. long bones (femur), short bones (carpals), flat bones (scapula), and sesamoid bones (patella)
  5. calcium
    one of the mineral constituents of bone. Calcium phosphate is the major calcium salt in bones
  6. cancellous bone
    spongy, porous, bone tissue in the inner part of the bone.
  7. cartilage
    flexible, rubbery connective tissue. It is found in the immature skeleton, at the epiphyseal growth plate, and on joint surface
  8. collagen
    dense, connective tissue protein strands found in bone and other tissues
  9. compact bone
    hard, dense bone tissue, usually found around the outer portion of bones
  10. condyle
    knuckle-like process at the end of a bone near the joint
  11. cranial bones
    skull bones: ethmoid, frontal, occopital, parietal, sphenoid, and temporal
  12. diaphysis
    shaft, or mid-portion, of a long bone
  13. disk (disc)
    flat, round, plate-like structure. An intervertebral disk is a fibrocartilaginous substance between two vertebrae
  14. epiphyseal plate
    cartilaginous area at the ends of long bones where lengthwise growth takes place in the immature skeleton
  15. epiphysis
    each end of a long bone; the are beyond the epiphyseal plate
  16. facial bones
    bones of the face;lacrimal, mandibular, maxillary, nasal, vomer, and zygomatic
  17. fissure
    narrow, slit-like opening in or between bones
  18. fontanelle
    soft spot (incomplete bone formation) between the skull bones of an infant
  19. foramen
    opening or passage in bones where blood vessels and nerves enter and leave. The foramen magnim is the opening of the occipital bone through which the spinal cord passes
  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)
