2. Bone Structure (pg 2)

3. Functions of the Bones
1. Support: Form internal framework that
supports the body

4. Functions of the Bones
1. Support: Form internal framework that
supports the body
2. Protection: Protects organs

5. Functions of the Bones
1. Support: Form internal framework that
supports the body
2. Protection: Protects organs
3. Movement: Skeletal muscles use bones as
levers

6. Functions of the Bones
1. Support: Form internal framework that

2. Protection: Protects organs
3. Movement: Skeletal muscles use bones as
levers
4. Storage: Marrow stores fat. Bone tissue
stores calcium and phosphorus

5. Blood cell formation: Occurs in bone marrow

8. Bone Tissue
• Compact Bone: Contains haversiancanals that
carry blood vessels surrounded by concentric
rings of matrix that contains osteocytes in
lacunae

9. Bone Tissue
• Compact Bone: Contains haversiancanals that
carry blood vessels surrounded by concentric
rings of matrix that contains osteocytes in
lacunae
• Spongy Bone: Less dense than compact bone.
Contains thin columns of bone tissue
surrounded by small, irregular cavities. The
cavities are filled with red bone marrow,
which forms red and white blood cells.

11. Parts of a long bone
1. Diaphysis: cylindrical main portion of a bone.
Made of compact bone

12. Parts of a long bone
1. Diaphysis: cylindrical main portion of a bone.

3. Articularcartilage: Thin layer of hyaline
cartilage covering the epiphysis. Reduces
friction at joints
