Two criteria that would identify the three muscle tissues are myofibers and nuclei.
There are three types of muscles:
1. Skeletal-Contains many nuclei along the length of the muscle cell. The nuclei are displaced peripherally. The skeletal fibers are arranged parallel. The myofibril is composed of bands.
2. Smooth-This tissue contain spindle-shaped cells with a single central nucleus. Smooth muscle fibers are shorter than skeletal.
3. Cardiac-The fibers of cardiac muscle are not simply parallel. Cardiac muscle fibers are long cylindrical cells with one or two nuclei.
ATP or Adenosine triphosphate is well know for it's energy source but despite it has many roles in cell. ATP is primarily used as energy source as it has higher energy in it's phospho-di-ester bonds between P and P atoms. It is hydrolyzed to ADP & AMP to give energy.
