Major Functions of the skeletal system are:
1. Support
2. Protection
3.Muscle attachments
4. Production of blood cells & Platelets
5. Storage

Types of Joints:
Hinge: Preforms a simple open and close motion.
Ex. Elbow, knees, jaw
Pivot: Are found between the axis an atlas vertebrae.
Ex. Allows head to move side to side
Ball and socket: Allows movement front to back and side to side.
Ex. Hips

Bone Marrow:
A soft fatty substance in the cavities of bones, in which blood cells are produced.
- Red marrow is found mainly in the flat bones such as hip bone, breast bone, skull, ribs, vertebrae and shoulder blades.
- Yellow marrow is found only in the vertebrae, hips, breastbone, ribs, and skull and at the ends of the long bones of the arm and leg.
Difference?
That red marrow is primarily for blood cell formation and yellow marrow is used for fat storage.

How does it work in conjunction with other systems?
Circulatory - The red and white blood cells are necessary for the body to function properly, unless the marrow is created, then it won't work.
Muscular - The bones are necessary for the muscles to be attached to, they are attached by various tendons and ligaments.

Ossification?
The process in which cartilage begins to form into bone.

Fun Facts!!!!!
1. Babies have about 300 components of cartilage, compared to the adult skeleton which has about 206.
2. Hands and feet make up 106 of your overall bones.
3. The Hyoid is the only bone that does not connect to another.
4. Teeth are not bones but are considered part of the skeletal system.
5. The longest bone in the human body is the thigh bone called the femur.
Diseases
Leukemia: This is a cancer of the white blood cells.
Osteoporosis: This is a disease in which the bones become fragile and prone to fracture.
