13. Bones are made up of different layers
Outer Membrane: thin and tough, it covers all of the bone except the ends
Blood vessels and nerves enter and leave the bone through the membrane
Compact Bone: hard and dense but not solid
Small canals carrying blood vessels and nerves from the bone’s surface to the
living things within the cell. Blood vessels and nerves run through the compact bone
Spongy Bone: lightweight and strong
Located just inside the compact bone and also found at the ends of the bone
Like a sponge, spongy bone has small spaces within it
Bone Marrow-soft connective tissue found in the spaces in bone
Two types of bone marrow:
Red marrow-produces blood cells
Yellow marrow-stores fat that serves as an energy reserve

14. Joints of the Skeleton
A Joint is a place in the body where two bones come together
Joints allow bones to move in different ways.
There are two kinds of joints in the body:
Immovable
Movable
Immovable joints connect bones in a way that allows little or no movement
Ex: the bones of the skull are held by immovable joints
the ribs attach to the sternum by immovable joints
Movable joints allow the body to make a wide range of movements

16. Four Types of Movable Joints
Ball and socket joint-allows the greatest range of motion
Lets you swing your arm and leg freely in a circle
Located in your shoulder and hips
Pivot joint-allows one bone to rotate around another
Lets you turn your head from side to side
Located in the top of your neck
Gliding joint-allows one bone to slide over another
Lets you bend and flex your wrist and make limited side to side motion
Located in your wrists and ankles
Hinge joint-allows forward and backward motion
Lets you bend and straighten your arms and legs
Located in your elbows and knees
