axial skeleton all bones that lie on or near the central axis of the body
appendicular skeleton all the upper and lower extremities
Sesamoid bone consist of body and two ends or extremities, found only in appendicular skeleton
Long bone consist of body and two ends or extremities, found only in appendicular skeleton
short bone roughly cuboidal shaped and found in wrists and ankles
flat bone consists of 2 plates of compact bone with cancellous bone marrow between them
irregular bone bones that have peculiar shapes that don't have a definitive category
hyaline cartilage found within the covering over ends of bones
articulating cartilage found within the covering over ends of bones
cancellous and compact bone What is short bones composed of?
compact bone, cancellous bone, medullary cavity, perioustem, and hyaline cartilage what is the long bone composed of?
compact bone, cancellous bone, bone marrow what is flat bone composed of?
intramembranous and endochondral what are the types of bone formation
intramembranous what type of ossification replaces membranes into bone?
endochondral what type of ossification replaces cartilage into bone?
intramembranous ossification ossification that occurs rapidly and takes place in bones needed for protection
endochondral ossification slower ossification that is slow and occurs in most parts of the skeleton especially the long bones
diayphysis the primary center of ossification is called
body diaphysis creates what part of the bone?
epiphysis secondary center of ossification is called
near the ends of limbs of long bones epiphysis creates what part of the bone
Epiphyseal plates what is the wider portion of a long bone adjacent to epiphyseal plate?
Metaphysis what is the wider portion of a long bone adjacent to epiphyseal plate?
periosteum a fibrous membrane that covers the outer surfaces of bone, contains a network of blood vessels
articular cartilage covers only at the joint surfaces at the ends of bone and acts as a protective cushion
diaphysis main shaft like portion of bone
epiphysis end portion of the bone
medullary cavity hollow, tubelike structure within the diaphysis
endosteum inner membrane that lines the medullary cavity
compact bone type of bone that is the outer layer of bone that appears dense and structureless
compact bone type of bone that contain haversian systems
cancellous bone type of bone composed of marrow-filled spaces separated by trabeculae
trabeculae thin processes of bone
epiphyseal plate separates the epiphysis and diaphysis
metaphysis where the diaphysis meets the epiphyseal growth plate
endochondral ossification what increases the length of a developing bone?
osteoclasts and osteoblasts what increases the diameter of bone?
cartilage resilient semi rigid form of CT that form parts of skeleton when more flexibility is required
hyaline cartilage type of cartilage that covers articulating surfaces
articular cartilage hyaline cartilage when it covers the ends of bones
medullary cavity hollow portion in long bone
endosteum inner membrane that lines the medullary cavity
trabeculae meshwork of interconnecting spaces that often follow lines of stress within bone
trabeculae what is produced when deposition of Ca salts in organic bone matrix?
nutrient artery passes obliquely through compact bone
fontanels membranous gaps that occur at birth
metaphysis bone production in childhood that occurs at side of the plate nearest the shaft
red bone marrow what produces red blood cells
yellow bone marrow what produces fat cells
condyle rounded process at an articular end
coracoid/coronoid beak-like or crown-like process
crest ridgle-like process
epicondyle projection above a condyle
facet small, smooth-surfaces articular process
hamulus hook shaped process
head hornlike process
line linear elevation, not as prominent as a crest
malleolus club shaped process
protuberance projecting prominence

trochanter either of the 2 large, rounded, and elevated processes of proximal femur
tubercle or tuberosity small, rounded, and elevated process
fissure cleft or deep groove
foramen hole in bone
nutrient foramen hole in bone for transmission of vessels and nerves
fossa pit, fovea or hollow space
froove shallow linear channel
meatus tubelike passageway
notch indentation in the border of a bone
sinus recess, groove, cavity or hollow space
sulcus furrow or trench
