1. Musculoskeletal System

2. Part 1: Skeletal System
What is its purpose?
Provide frame and support for all the other body systems
Aids in movement
Provides protection
Site of mineral storage
Site of blood cell formation
Makes up bones, cartilage and connective tissue

3. Structures found in the skeletal system
Bone
Cartilage
Joints
Ligaments and Tendons

4. Bones are comprised of:
26% minerals (mostly a compound containing calcium
50% water
4% Fat
20% protein
Put that statement in your own words
Bone strength and grown are determined by an animals ration.

5. There are 4 types of bones:
Long bones
Short bones
Flat bones
Irregular bones

6. Long Bones Serve as support columns
Provide support for the body giving it the rigidity (hardness) necessary to stand and move
Example: Leg Bones

7. Short Bones Shaped like a cube Often as big around as they are long
Located in complex joints, such as the knee and hock
Serve as hinges
Protect long bones by being flexible
Cushion shock
Diminish friction
Example: Hock, Knee

8. Flat Bones Relatively thin and flat and usually curved
Protect vital organs such as the brain, the heart, and the lungs
Are longer and wider than they are thick
Usually multiple bones fused together
Example: Scapula, Skull, Ribs

9. Irregular Bones Irregularly shaped
Important to the protection and support of the central nervous system
Points of some muscle attachment
Example: Vertebrae
These bones make up the backbone, which is not a single bone, but a series of irregular bones. They flex and bend to give the animal movement.
