- 1Functions of the Skeletal System.· Support of the body
· Protection of soft organs
· Movement due to attached skeletal muscles
· Storage of minerals and fats
· Blood cell formation - 2Four main bonesLong Bone
Short Bone
Flat Bone
Irregular Bone - 3Label this long bone
- 4Diaphysisshaft, compact bone
- 5Periosteuma dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints
- 6Epiphysisend consisting of thin compact bone enclosing spongy bone
- 7Articular cartilagecovers the epiphysis, is hyaline cartilage, prvides smooth slippery surface
- 8Epiphyseal line in adultsseparating the epiphysis from the diaphysis
- 9Medullary cavity, or yellow marrowstores adipose tissue in adults, is red marrow in infants. Red Marrow is in spongy cavities of flat bones and epiphyses of some long bones in adults

- 21Fibrous Joints Tissue? Cavity? Movement?Bones united by fibrous tissue
no joint cavity
Mostly immovable
- 22Cartilaginous Joint Tissue? Cavity? Movement?Connected by Cartilage
No joint cavity
Slightly movable
- 23Synovial Joint Tissue? Cavity? Movement?Articular cartilage separates, joint cavity
Synovial fluids is in cavity
Fluid lubricates the joint
Very movable

Joint surfaces are enclosed by a fibrous articular capsule
Have a joint cavity filled with synovial fluid
Ligaments reinforce the joint - 26—
