Flashcards in Skeletal System overview Deck (10):
Cartilage matrix components
Polysaccharides, protein fibers, inorganic salts
What germ layer gives rise to dermal bone?
Dermatome epimere mesoderm (dermis) mesenchyme
Similarities between cartilage and bone
-Living cells in solid matrix
-Matrix includes protein fibers, inorganic salts
Difference between cartilage and bone with respect to nutrients reaching cells
Bone: supplied by blood vessels
Cartilage: no vessels, relies on diffusion
How does dermal bone form?
In sheets or 'membranes', directly
Bone matrix components
Inorganic salts, protein fibers
Functions of the skeletal system
1. Structural Support
2. Protect vital organs
3. Movement (lever system for muscles to pull on)
How does replacement bone form?
Hyaline cartilage is initially laid down, then ossifies
2 primary types of tissue in skeletal system
