Question:
Canaliculi
Answer:
small canals that connect the lacunae with each others, which is also connected to central canal
of Haversian system (passage ways between lacunae-using it as a way to communicate)

Question:
intersitial lamellae
Answer:
fill the gaps between forming osteons or are leftovers of osteons that were partially destroyed by
bone remodeling (finds the in between the spaces of the osteons)

Question:
circumferential lamellae
Answer:
sheets of bone located just deep to periosteum; extend around entire circumference of shaft (wrap
around the outside of the bone

Question:
central (haversian canal
Answer:
runs up the middle

Question:
perforating (volkmann's) canal
Answer:
perpendicular to long axis of bone and to haversian canals (link the various central canals)




1

,Question:
microscopic structure of spongy bone
Answer:
contains trabeculae, lamellar arranged osteocytes and canaliculi -trabeculae arranged along lines
of stress; helps bone to resist stress -trabeculae only a few cell layers thick; contain irregularly
arranged lamella and osteocytes interconnected by canaliculi -there are no osteons -nutrients
diffuse through canaliculi from the marrow spaces between the trabeculae to reach osteocytes

Question:
intramembranous ossification
Answer:
bone develops from a fibrous CT membrane containing mesenchymal cells

Question:
-cranial bones of the skull nad the clavicles-these are flat bones -begins at about 8 weeks of
embryonic development
Answer:



Question:
Endochondrally ossification
Answer:
bone development via the replacement of a hyaline cartilage model -all bones below the skill
(expect the clavicles) -begins in second month of development

Question:
what happens to the hyaline cartilage when the secondary ossification is complete?
Answer:
1) on the epiphyseal surfaces as the articular cartilages 2) at the junctions of diaphysis and
epiphyses where it forms the epiphyseal plates- this is the area where long bones continue to
grow




2

, Question:
what happens during infancy and youth to bone growth?
Answer:
long bones lengthe entirely by interstital growth of the epiphyseal plates and all bones grow in
thickness by appositional growth -most bones stop growing during adolescence or in early
adulthood- some facial bones continue to grow throughout life

Question:
describe the way bones grow
Answer:
the ends of the bones are reshaped as they grow. (remeber that the epiphyseal plates are located
in the wider parts of long bones) bones must be reshaped to be incorporated into the disphysis
but the has to get strong and thick as the bone lengthens

Question:
SUMMARY: bone is destroyed by osteoclasts and laid down by osteoblasts on both the inner
and outer surfaces of a growing long bone
Answer:



Question:
bone remodeling
Answer:
hte epiphyseal plate stays the same size throughout childhood and adolescence

Question:
the plate then becomes thinner (cartailge cells in zone 1 multiply more and more slowly)
Longitudinal growth ends when the bone tissue of the epiphysis and disphysis fuses
