Formation of the bony skeleton begins when?
5 weeks of embryo development
6 weeks of embryo development
2 weeks of embryo development
8 weeks of embryo development
Intramembranous Ossification
Bone develops by replacing cartilage
Bone develops from cartilage membrane
Bone develops from fibrous membrane — membrane bone
Bone develops by replacing connective tissue
What does intramembranous ossification form?
Cranial bones of the skull (frontal, parietal, occipital, temporal), and collar bone
All bones below the skull
Trick question: it doesn’t form any bones
All bones apart of the bone chart
Intramembranous ossification bone shape
Irregular
Flat
Long
Proximal
Supporting structures of Intramembranous ossification
Mesenchymal (middle layer) cells
Areolar (irregular dense connective tissue) cells
Areolar (dense connective tissue) cells
Chrondrocytes (cartilage) cells
Endochondral ossification
Bone forms from fibrous membrane
Bones form from citrus membrane
Bone forms by replacing hyaline cartilage
Bone forms by replace Areolar cartilage
What does endochondrial ossification form?
Trick question: it doesn’t form any bones
All bones from the tarso up
Cranial, pariteal , and collar bone
All bones below the skull
What does endochondral ossification do?
Uses hyaline cartilage “bones” formed earlier as models or patterns for bone construction
Uses Areolar tissue “ctp” formed earlier as models or patterns for bone construction
Uses fibrous membrane “membrane bone” formed earlier as models or patterns for bone construction
Uses elastic cartilage “stretch” formed earlier as models or patterns for bone construction
Formation of bone order
1) bone collar 2) hollow hyaline cartilage model 3) invasion of internal cavities 4) formation of the medullary cavity 5) ossification of epiphyses
1) ossification of epiphyses 2) formation of the medullary cavity 3) invasion of internal cavities 4) hollow hyaline cartilage model 5) bone collar
It does go in an order. They all happens at the same time once the embryo reaches 8 seeks
1) invasion of internal cavities 2) hollow hyaline cartilage model 3) ossification of epiphyses 4) formation of the medullary cavity 5) bone collar

Lengthen, appendicular
Thicken, interstitial
Thicken, lengthen
Length, interstitial
Long bones ___ by ___ growth
Thicken, interstitial
Lengthen, appositional
Thicken, appositional
Lengthen, interstitial
Cartilage proximal to the epiphyseal plate is relatively..
Active
Dead
Inactive
Alone
Cartilage closest to the diaphysis organizes into a pattern that allows..
Slow and in efficient growth
Fast and inefficient growth
Fast and efficient growth
Slow and efficient growth
Growth zone cells are located at..
The bottom of the stack facing the epiphyses
The top of the stack facing the epiphyses
The middle of the stack facing the epiphyses
The corner of the stack facing the epiphyses
When cartilage cells undergo mitosis, what do they do?
Push the epiphyses away from the diaphysis
Push the epiphyses away from the proximal
Push the epiphyses in the correct way
Doesn’t push the epiphyses, it pulls it away from the proximal
What happens during the transitional zone?
Older cells enlarge, matrix becomes calcified, cartilage cells die, and the matrix deteriorates
Younger cells enlarge, matrix becomes incalcified, fibrous cells die, and the matrix deteriorates
Younger cells enlarge, matrix cells becomes calcified, cartilage cells die, and the matrix deteriorates
Older cells shrink, matrix becomes incalcified, fibrous cells die, and the matrix deteriorates
What happens during the osteopenic zone?
New cartilage formation
New tissue formation
New growth formation
New bone formation
What type of growth is in width of long bones?
Interstitial
Lateral
Appositional
Distal
Osteoblasts beneath the periosteum do what?
Secrete blood on the external surface
Secrete matrix on the external surface
Secrete tissue on the external surface
Secrete matrix on the internal surface
Why do osteoclasts remove bone?
To prevent bone from being too small
To prevent bone from being too heavy
To prevent bone from being too damaged
To prevent bone from being too thin
What controls bone growth?
Cartilage tissue
Fibrous tissue
Growth hormone
Elastic tissue
During puberty, testosterone and estrogen do what?
Initially promote adolescent growth spurts
Cause masculinization and feminization of specific parts of the skeleton
End longitudinal bone growth
Later induce epiphyseal plate closure
Increase blood and food intake
