Chapter 5 Skeletal Flashcards
Identify the components of the skeletal system, and their functions
- Bone
- Cartilage
- Ligaments - Bone to Bone
- Muscle to Bone
the functions of bone
Produce blood cells
Stores Minerals
The two layers of bone
- Compact Bone - Dense mineralized outer layer
- Spongy Bone - Inner layer with marrow
Periosteum
Fibrous outer covering of the bone
F: Repair bone and bone growth
Draw the structe of an Osteon
1. Osteocytes
2. Central Canal
3. Lacuna
4. Canaliculi
3 Cells found in bone
- Osetoblasts
- Osteocytes
- Osteoclasts
Difference between Diaphysis and Epiphysis
Diaphysis - Long shaft
Epiphysis - End of the bone
immature cells that secrete calcified material (bone building cells) are
Osetoblasts
