Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:
Skeletal muscle cells - striated, voluntary control
Cardiac muscle cells - striated, involuntary control
Smooth muscle cells - nonstriated, involuntary control
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.
In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.
The terms muscle cell and muscle fiber are synonymous.
