the bones of the arms, legs, and girdles (bones that attach the arms and legs to the trunk)
Foramen Magnum
a large opening in the occipital bone that allows the spinal cord to exit the cranial cavity

calcium phosphate mineral salt that makes up the mineral matrix of bone connective tissue
Osteon (Haversian system)
target-like arrangement of bone connective tissue found in compact bone

fibrous joint formed by an interosseus membrane between the radius and the ulna or between the tibia and the fibula
Hinge
joint is very movable in one direction ex. elbow
Ball and Socket
the ball of one bone fits into a socket of another, movable in all directions ex. hip

(dual-energy x-ray absorptiometry) the use of low-dose radiation to measure bone density in the hip and vertebrae
X-ray
the use of electromagnetic radiation that sends photons through the body to create a visual image of dense structures such as bone
Osteoporosis
condition characterized by a severe lack of bone density
Osteomyelitis
a bone infection
