Skeletal System overview Flashcards
1
Q
Cartilage matrix components
A
Polysaccharides, protein fibers, inorganic salts
2
Q
What germ layer gives rise to dermal bone?
A
Dermatome epimere mesoderm (dermis) mesenchyme
3
Q
Similarities between cartilage and bone
A
- Connective tissue
- Living cells in solid matrix
- Matrix includes protein fibers, inorganic salts
4
Q
Difference between cartilage and bone with respect to nutrients reaching cells
A
Bone: supplied by blood vessels
Cartilage: no vessels, relies on diffusion
5
Q
How does dermal bone form?
A
In sheets or ‘membranes’, directly
6
Q
Bone matrix components
A
Inorganic salts, protein fibers
7
Q
Functions of the skeletal system
A
- Structural Support
- Protect vital organs
- Movement (lever system for muscles to pull on)
8

How does replacement bone form?
A
Hyaline cartilage is initially laid down, then ossifies
