Flashcards in Skeletal System overview Deck (10):
1

Cartilage matrix components

Polysaccharides, protein fibers, inorganic salts

2

What germ layer gives rise to dermal bone?

Dermatome epimere mesoderm (dermis) mesenchyme

3

Similarities between cartilage and bone

-Connective tissue
-Living cells in solid matrix
-Matrix includes protein fibers, inorganic salts

4

Difference between cartilage and bone with respect to nutrients reaching cells

Bone: supplied by blood vessels
Cartilage: no vessels, relies on diffusion

5

How does dermal bone form?

In sheets or 'membranes', directly

6

Bone matrix components

Inorganic salts, protein fibers

7

Functions of the skeletal system

1. Structural Support
2. Protect vital organs
3. Movement (lever system for muscles to pull on)

8

How does replacement bone form?

Hyaline cartilage is initially laid down, then ossifies

9

2 primary types of tissue in skeletal system

Cartilage, bone

10

2 types of bone

Dermal, replacement
