Which of the following is a function of the bone?
internal support and protection
provide attachment for muscles
calcium and phosphate storage
red blood cell formation
Tendons
are surrounded by connective tissue called peritendineum
are composed of collagen fibers oriented in the same direction
are produced bu lacunae cells
cause tendinitis
Chondrocytes are mature cartilage cells found within in the _______ and they are derived from ________
perichondrium, fibroblasts
perichondrium, chondroblasts
lacunae, fibroblasts
lacunae, chondroblasts
Cartilage
often occurs in thin plates or sheets
receives nutrients and oxygen by diffusion
grows as a result of chondroblast formation by the perichondrium
none of the choices
Which of the following substances make up the major portion of bone?
collagen
hydroxyapatite
osteocytes
osteoblasts
The flexibility of bone is due to
osteoclasts
ligaments
calcium salts
collagen fibers
Which of the following connective tissue membranes cover the surface of mature bones?
periosteum
perichondrium
hyaline cartilage
fibroblasts
A fracture in the shaft of a bone would be a break in the
epiphysis
perichondrium
diaphysis
articular cartilage
The portion of the long bone that stores yellow marrow in adults is the
medullary cavity
spongy bone
compact bone
epiphysis
Haversian canals
connect Volkmann's canals to canaliculi
connect spongy bone to compact bone
is where red blood cells are produced
are found only in spongy bone
What type of lamellae is found in osteons?
circumferential lamellae
concentric lamellae
insterstitial lamellae
cuboidal lamellae
Intramembranous bone fromation
occurs in the epiphyseal plate
gives rise to the flat bones of the skull
is responsible for bone growth in diameter
occurs within the hyaline cartilage model
The ossification regions formed during embryonic development are
secondary ossification centers
primary ossification centers
cartilage at the ends of bones
medullary cavities
Articular cartilage
is found in the ends of bone
is hyaline catilage
is embryonic cartilage that does not ossify
is at the diaphysis
Growth in the length of bone occurs
at primary ossification center
beneath the periosteum
at the diaphysis
at the epiphyseal plate
The prime function of OSTEOBLASTS is to
prevents osteocytes from forming
resorb bone along the epiphyseal plate
inhibit the growth of bone
be involved in the production salts and collagen fibers
The prime function of OSTEOCLASTS is to
prevent osteoblats from forming
breakdown bone
secrete calcium salts and collagen fibers
form compact bone
in a bone that is no longer growing, where would one be most likely to find an osteoclast?
under the periosteum
epiphyseal plate
articular cartilage
Volkmann's canal
Destruction and remolding of bone may occur
as bones change shape during growth
as bones are subjected to varying patterns of stress
during and following the healing of fractures
when a bone is no longer growing
In the healing of bone fractures
a blood clot forms around the break
a callus is formed
both intramembranous and endochondral ossification are involved
the callus may eventually disappear
