1. The Skeletal System: Bones and Joints

2. Functions of the Skeletal System (Bones)
Support
Protection
Leverage System/movement
Mineral Storage
Blood Cell Formation

3. Function of the Skeletal System (Cartilage)
Model for Bone Growth (Bone development)
Smooth Joint Surfaces
Support

4. Function of the Skeletal System (Tendons and Ligaments)
Tendon: Attach muscles to bone
Ligaments: Attach bone to bone
Assist with Movement
Structure and Support

5. The Skeleton Structure of the Skeleton 206 bones
Bone, cartilage, tendons, and ligaments are all types of connective tissue
Axial Skeleton: Supports the central axis of the body
Skull, vertebral column, and rib cage
Appendicular skeleton:
Arms, legs, pelvis and shoulder

7. Skeletal Bones to Know

8. Types of Bones 4 Types of bones Long Bones: Femur, Humorous
Short Bones: Carples, and Tarsals
Flat Bone: Thin bones, skull bones, ribs, scapulae
Irregular Bones: Vertebrae, facial bones

9. Bone Structure Diaphysis: Central Shaft
Epiphyseal Plate/Growth Plate: At the end of the bone (site for bone growth)
Articular Cartilage: Cartilage that covers the bone where it comes in contact with another bone

10. Bone Surface
Periosteum: Dense connective tissue that covers and protect the bone
Endosteum: Lines the medullary cavity (cavity of the diaphysis)

11. Bone Cavities
Medullary Cavity: Major cavity in the diaphysis of the bone.
Yellow Marrow: Consists mostly of fat
Red Marrow: Consists of blood-forming cells (only site of blood formation)

12. Bone Make Up Bones are made up or composed of
Compact Bone: Solid Bone located in the diaphysis, contains Haversian Cannal’s that supply nerves and blood vessels
Cancellous/Spongy Bone: Looks like a sponge, located at the epiphyses
