The process of bone
formation
What is osteogenesis or
ossificaton
Bone deposit is
accomplished by
What are osteoblasts
A type of bone
development in which a
cartilage “model” must
be replaced by bone
What is endochondral
ossification
Hormones affecting
bone development.
What are growth
hormone, thyroid
hormone and sex
hormones
Growth in diameter
(thickness) of long
bones
What is appositional
growth
The breakdown of bone
is accomplished by
What are osteoclasts
DOUBLE JEOPARDY
Two regulators of bone
remodeling
What is the hormone
feedback loop
(calcitonin and PTH) and
responses to mechanical
forces (Wolff’s Law)
Classification of a
fracture based on the
orientation of the break
What is linear or
transverse
Mineralization of bone
generally refers to
Calcification, in which
calcium crystals are
packed together
forming the hard
compact bone
Bone remodeling occurs
here
Where is the periosteal
and endosteal surfaces
Bone resorption and
bone deposit together
are referred to as
What is bone
remodeling
This disorder literally
means “soft bones”
What is osteomalacia
This disorder can cause
bowing of the legs in
young children
What is rickets
Osteoporosis can be
treated with hormone
replacement therapy
because
What is estrogen
promotes bone growth
Smoking is a risk factor
for osteoporosis
because.
What is smoking
decreases estrogen
levels
The long axis of a bone
What is the diaphysis
DOUBLE JEOPARDY
The membrane that
covers compact bone
What is the periostem
The structural unit of
compact bone
What is the osteon
The concentric circles
that make up an osteon
What are lamella
The channels that
connect one lacunae to
another
What are canaliculi
Bone cells
What are osteocytes
Realignment of bones in
which the physician
coaxes the bones into
place
What is closed reduction
Acids secreted in
resorption bays act to
What is convert calcium
crystals into soluble
calcium that can diffuse
into the blood
A disorder in which
bone resorption
outpaces bone deposit
leading to weak and
brittle bones
What is osteoporosis
Calcification occurs at
this zone of the
epiphyseal plate.
What is the osteogenic
zone
