Muscles are classified into there types. They are :
1) Voluntary muscle
2) Involuntary muscle
3) Cardiac muscle
1) Voluntary muscle (striated or skeleton muscle) : It is under the control of will. It forms the flesh of limbs and trunk. It contains unbranched fibers called my of brills.
These fibers are cylindrical in shape containing :
a) distinct striations
b) a number of nuclei. Each fiber is surrounded by a thin membrane called sarcolemma.
2) Involuntary muscle (non -striated, plaino smooth muscle) : It is not controlled by will . It is present in intrnal organs like stomach, intestine and uterus. It contains long spindle shaped fibres with a central nucleus. The fibres are not striated and are not covered by any membrane. But they are joined by a loose connective tissue. These muscles are controlled by autonomic nervous system.
3) Cardiac muscle: It is found only in the heart. It consists of Short, cylindrical and blanched fibres. The nucleus is centrally placed. The striations are vague. The cardiac muscle is not controlled by will. But it contracts automatically in a rhythmic manner.
