Muscles and Their Types -
- Muscle is a specialised tissue of mesodermal origin.
- About 40-50 percent of the bodyweight of a human adult is contributed by muscles.
- They have special properties like excitability, contractility, extensibility and elasticity.
- Muscles have been classified using different criteria, namely location, appearance and nature of regulation of their activities.
- Based on their location, three types of muscles are identified :
- (i) Skeletal
- (ii) Visceral and
- (iii) Cardiac
Visceral Muscles:
- Visceral muscles are located in the inner walls of hollow visceral organs of the body like the alimentary canal, reproductive tract, etc.
- They do not exhibit any striation and are smooth in appearance.
- Hence, they are called smooth muscles (nonstriated muscle).
- Their activities are not under the voluntary control of the nervous system and are therefore known as involuntary muscles.
- They assist, for example, in the transportation of food through the digestive tract and gametes through the genital tract.

Visceral muscles assist in the transportation of food through the digestive tract and gametes through the genital tract. Hence, the correct option is visceral muscles
