1. | They are located in the inner walls of hollow visceral organs of the body like the alimentary canal, reproductive tract, etc. |
2. | They do not exhibit any striation and are smooth in appearance, hence, they are called smooth muscles (nonstriated muscle). |
3. | Their activities are under the voluntary control of the nervous system and are therefore, known as voluntary muscles. |
