calcium
one of the mineral constituents of bone
cancellous bone
spongy porous, bone tissue in the inner part of a bone
cartilage
flexible, connective tissue
found in the immature skeleton, at the epiphyseal growth plate, and on joint surfaces
collagen
dense, connective tissue protein strands found in bones and other tissues (ligaments, tendons, skin)
compact bone
hard, dense bone tissue, usually found around the outer portion of bones
cranial bones
skull bones: sphenoid, temporal, ethmoid, parietal, occipital, frontal (STEPOF6)
diaphysis
shaft or mid portion of a long bone
disc
flat, round, plate like structure
epiphyseal plate
cartilaginous area at the ends of long bones where lengthwise growth takes place in the immature skeleton
epiphysis
each end of a long bone
area beyond the epiphyseal plate
facial bones
bones of the face: lacrimal, mandibular, maxillary, nasal, vomer, and zygomatic
fontanelle
soft spot between the skull bones of an infant
foramen magnum
opening of the occipital bone through which the spinal cord passes
haversian canals
minute spaces filled with blood vessels
ligament
fibrous connective tissue that binds bones to other bones
malleolus
round process on both sides of the ankle joint
manubrium
upper portion of the sternum
mastoid process
rounded projection on the temporal bone behind the ear
medullary cavity
central, hollowed out area in the shaft of a long bone
metaphysis
flared portion of a long bone between the diaphysis and the epiphyseal plate
olecranon
large process on the proximal end of the ulna at the elbow
orthopedist
medical doctor who specializes in bone, joint, and muscle conditions
osseous tissue
bone tissue
ossification
process of bone formation

sinus
hollow air cavity within a bone
styloid process
pole like process extending downward from the temporal bone on each side of the skull
suture
immovable joint between bones
temporomandibular joint
connection on either side of the head between the temporal bone of the skull and mandibular bone of the jaw
tendon
fibrous connective tissue that binds muscles to bones
trabeculae
supporting latticework of bony fibers in cancellous bone
vertebra
individual segment of the spine composed of the vertebral body, vertebral arch, spinous process, transverse process, and lamina, enclosing the neural canal and spinal cord
xiphoid process
lower, narrow portion of the sternum
yellow bone marrow
fatty tissue found in the medullary cavity of most adult long bones
