=The Skeletal System= Jobs
 * bones
 * joints
 * shape and support body
 * protect your organs
 * help you move

media type="custom" key="8932624" Your skeleton is made of 206 bones. There are 80 bones in your **axial** skeleton, or skull, spine, ribs, and sturnum. There are 126 in your **appendicular** skeleton, or arms, legs, pelvis, and shoulders.

There are three main types of joints that allow you to move: immovable joints, slightly movable joints, and freely movable joints. Your skeleton works with other body systems in many ways:
 * **Movable Joint** || **Type of movement** || **Examples** ||
 * __Ball-and-socket__ || all types || shoulders and hips ||
 * __Pivot__ || rotation || top of spine ||
 * __Hinge__ || bending and straightening || elbows, knuckles, fingers, toes ||
 * __Gliding__ || sliding || wrists, ankles ||
 * __Saddle__ || rotation, bending, straightening || base of thumbs ||
 * Muscular system & skeletal system work together to enable your body to move.
 * Circulatory system & skeletal system work together to make blood and platelets that deliver oxygen to other organs.
