Bones are living tissue. •The skeleton is the body's framework and has two main divisions, the axial skeleton and the appendicular skeleton.
• Bones come together at joints.

The skull and crossbones flying from a pirate ship have long been a symbol of death. Therefore, you might think that bones are dead structures made of rocklike material. This isn't true. The bones in your body are very much alive!
Bones are living structures with 5 functions: protect internal organs support the body make blood cells store minerals provide for muscle attachment A point where two or more bones connect is called a joint.
There are two different types of joints in the body: Movable joints (like ball-and-socket, hinge, gliding and pivot
joints) Immovable joints (like the bones of the skull and pelvis)
which allow little or no movement

In each of your shoulders is a deltoid (say: del-toyd) muscle. Your deltoid muscles help you move your shoulders every which way — from swinging a softball bat to shrugging your shoulders when you're not sure of an answer.
The pectoralis (say: pek-tuh-rah-lus) muscles are found on each side of your upper chest. These are usually called pectorals (say: pek-tuh-rulz), or pecs, for short. When many boys hit puberty, their pectoral muscles become larger. Many athletes and bodybuilders have large pecs, too.
Major MusclesBecause there are so many skeletal muscles in your body, we can't list them all here. But here are a few of the major ones:
Below these pectorals, down under your rib cage, are your rectus abdominus (say: rek-tus ab-dahm-uh-nus) muscles, or abdominals (say: ab-dahm-uh-nulz). They are also sometimes called abs for short. When you make a muscle in your arm, you tense your biceps (say: bye-seps) muscle. When you contract your biceps muscle, you can actually see it push up under your skin.Your quadriceps (say: kwad-ruh-seps), or quads, are the muscles on the front of your thighs. Many people who run, bike, or play sports develop large, strong quads. And when it's time for you to take a seat? You'll be sitting on your gluteus maximus (say: gloot-ee-us mak-suh-mus), the muscle that's under the skin and fat in your behind!
