A muscle cell is a special kind of cell that makes up an organism's muscle tissues. The muscles allow independent movement and regulate biological functions such as digestion and heartbeat.keletal muscle structure. Different types of muscle tissue. An organism's muscle tissue is composed of muscle cells. Multi-unit smooth muscle cells operate independently and single-unit, or visceral, smooth muscle cells operate together as a unit.
All of this activity requires energy. Muscles use energy in the form of ATP. The energy from ATP is used to reset the myosin crossbridge head and release the actin filament. To make ATP, the muscle does the following: 1  Breaks down creatine phosphate, adding the phosphate to ADP to create ATP.et's take a look at what occurs within a skeletal muscle, from excitation to contraction to relaxation 1  : An electrical signal (action potential) travels down a nerve cell, causing it to release a chemical message (neurotransmitter) into a small gap between the nerve cell and muscle cell.
