what are muscles made of
All muscles are basically made of the same material, a kind of elastic tissue; packages of stretchable fiber-like material, similar to what goes into making a rubber band.Each muscle is made of thousands, and sometimes tens of thousands of small musculus fibers.triated muscles consist of thousands of sarcomeres-muscle units. The muscle has a striped (striated) appearance when viewed under a microscope because each sarcomere is made up of parallel bands of different materials. When various bands in the sarcomeres relax or contract, the whole muscle extends or relaxes.
