Sagot :

HERE'S THE ANSWER

  • 1.)Skeletal muscle is attached to bone, mostly in the legs, arms, abdomen, chest, neck, and face. Skeletal muscles are called striated (pronounced: STRY-ay-ted) because they are made up of fibers that have horizontal stripes when viewed under a microscope.
  • 2.)Muscles move body parts by contracting and then relaxing. Your muscles can pull bones, but they can't push them back to their original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
  • 3.)Bones: Bones of all shapes and sizes support your body, protect organs and tissues, store calcium and fat and produce blood cells. A bone's hard outside shell surrounds a spongy center. Bones provide structure and form for your body.
