Maryville
Bones .....ANSWER.....provide support and production for the
body's tissues and organs.
Important source of minerals and blood cells
Bone formation .....ANSWER.....begins during embryonic
development with the differentiation of mesenchymal cells into
either chondrocytes or preosteoblasts.
bone minerals either crystalize on a cartilage or become bone
forming cells w/out cartilage
,Page 2 of 44
Bone tissue .....ANSWER.....continuously being resorbed and
synthesized by bone-remodeling units of osteoclasts and
osteoblasts
RANKL .....ANSWER.....Receptor activator of nuclear factor
kappa-B ligand
includes osteoclast activation and bone resorption
OPG .....ANSWER.....osteoprotegerin
protein. attachment serves as a decoy receptor for RANKL and
blocks osteoclast activity
decreases bone resorption.
RANKL and OPG balance .....ANSWER.....Quality of bone
,Page 3 of 44
Bone composition .....ANSWER.....compact and spongy bone
tissue.
compact bone .....ANSWER.....highly organized into haversian
systems that consist of concentric layers of crystallized matrix
surrounding a central canal that contains blood vessels and
nerves.
crystallized matrix in compact bone .....ANSWER.....has concentric
layers with small spaces containing osteocytes. Canaliculi inter
connect the osteocyte space.
crystallized matrix in spongy bone .....ANSWER.....arranged in
bars or plates. spaces containing osteocytes are dispersed
between the bars or plates and interconnected by canaliculi
BMPs (bone morphogenic proteins) .....ANSWER.....involved in
multiple crucial functions in the skeletal system
how many bones in the body .....ANSWER.....206
, Page 4 of 44
divided into axial skeleton and appendicular skeleton
Bone Classification .....ANSWER.....long, short, flat, irregular
long bones .....ANSWER.....longer than they are wide. broad end
called epiphysis, broad neck called metaphysis, and narrow
midportion called diaphysis that contains the medullar cavity.
Hematoma .....ANSWER.....formation provides the fibrin
framework for formation and organization of granulation tissues
granulation tissue .....ANSWER.....provides a cartilage model for
the formation and crystallization of bone matrix
Remodeling .....ANSWER.....restores the original shape and size
to injured bone
joint .....ANSWER.....site of attachment of 2 or more bones.
provide stability and mobility of the skeleton
