- Three types of muscle viz., smooth, skeletal and cardiac are distinguishable histologically-
- Smooth or non-striated muscle lacks the cross striations seen in other two muscles. The smooth muscle is involuntary, being especially associated with viscera which are not under the voluntary control.
- Skeletal muscle is striated and voluntary making up the bulky muscles of the body.
- Cardiac or heart muscle is striated but involuntary.
