3facts about skeletal muscle, smooth muscle, and cardiac muscle

Skeletal muscle
• Individual muscles, such as the biceps in the arm, are made up of large numbers (about 100 000 in biceps) of giant cells, known as muscle fibres.
•Each muscle fibre is surrounded by a cell membrane.
• (A fact that)If oxygen is available, glucose can be oxidized to water and carbon dioxide, with two-thirds of the energy released used to rebuild the ATP supply.
