1 Skeletal System

2

3 Function of Skeletal System

4 Function of the Skeletal System A.Protection B.Movement C.Support D.Blood cell formation (hematopoiesis) E.Storage (fat and minerals)

5 Structure of the Skeletal System Axial Appendicular ne.htm

6 The Structure of Bone: Compact Bone & Spongy Bone Compact bone Forms outer part of bones Bears weight Spongy bone Made of trabeculae (latticework) Located inside bones Reduces weight of bone

7 Spongy or Compact?

8 4 Types of Bone Shapes Long bones Short bones Flat bones Irregular bones

9 Anatomy of a Long Bone epiphysis (head) diaphysis (shaft) epiphysis

10 Bone is a Living Tissue!!!

11 1.It is made of living cells embedded in a non-living matrix. 2.It grows, remodels and repairs. 3.It responds to hormonal stimulation.

12 Made of Living Cells Osteon Lacunae Canniculi

13 Matrix -minerals -proteins **strength and flexibility

14 Bone Cells Types Osteoblast – bone builders – form matrix Osteocyte – bone maintainers – maintain matrix Osteoclast – bone dissolvers – destroy matrix

15 Bone is a Living Tissue!!! 1.It is made of living cells embedded in a non-living matrix. 2.It grows, remodels and repairs. 3.It responds to hormonal stimulation.
