In the first stage endochondral Long bone formation, bone formation occurs first in the endochondrium of the diaphysis
False
The first step in intramembranous bone growth the formation of hyaline cartilage model
False
Which statement below is not true for cartilage and bone
both are avascular
The last step in the path to producing bone tissue
calcification of cartilage
In the first stage of endochondral long bone formation, the periosteal color forms in the epiphysis region
false
The first stage and endochondral long bone confirmation, bone formation occurs first in endochondrium of the diaphysis
false
The formation of the periosteal color occurs during the final stage of long bone growth
false
The fetal skeleton is first modeled as what type of cartilage before being replaced by bone
hyaline cartilage
During stage 3 of long bone growth, osteoclasts begin to lay down bone on calcified cartilage
true
During stage 3 of long bone growth, two secondary centers of ossification form in the epiphyseal area
true
During stage three of long bone growth, the rate at which calcified cartilage erodes and is replaced by spongy bone is the same rate at which cartilage cells of epiphyseal plate divide
true
Electron Micrographs shown that collagen fibers in bone have the same 64 nm banding pattern as shown by collagen fibers and other tissues
true
The mechanism of cartilage calcification is thought to involve the release of phosphate ions due to action of alkaline phosphatase in chondrocytes
true
If bone is placed in weak acid for an extended period of time, the resulting bone becomes
very flexible
The organic component of bone is composed primarily of
collagen fibers
Once the cartilage model in bone formation is calcified, the chondrocyte present in the cartilage
die
They Type of bone growth which starts as a cartilage model is called
endochondral
During stage three of long bone growth, epiphyseal plates form but disappear after birth
false
Formation of the periosteal collar occurs during the final stage of long bone growth
false
In the first stage of endochondral Long bone formation, the periosteal collar forms in the epiphysis region
false
The type of bone growth exhibited by the flat bones of the skull in which bone is laid down on areas where there are many collagen fibers is called
intramembranous
The process of bone formation, hyaline cartilage arises from
mesenchyme
The type of bone cell responsible for the secretion of bone matrix and found in areas of new bone formation is called
osteoblast
The type of bone cell responsible for the secretion of the bone matrix and found areas of new bone formation is called an
osteoblast
Mesenchyme cells follow blood vessels into the diaphysis of the growing long bone and to differentiate into
osteoblasts
During stage two of long bone gross, blood vessels migrate into the center of the diaphysis through holes in the periosteal color formed by erosion of bone by
osteoclasts
The type of bone cell formed by blood monocytes and having from 15 to 20 nuclei Per cell which participates in bone reabsorption is called and
osteoclasts
The type of bone cell found in a fully formed bone which lives in small spaces called lacunae is called an
osteocyte
A boney latticework called trabeculae can be seen in
spongy bone
