Question

Which one of the following statement is incorrect?

• A. Heart muscles are striated and involuntary
• B. The muscles of the hands and legs are striated and voluntary
• C. The muscles located in the inner walls of the alimentary canal are striated and involuntary
• D. Muscles located in the reproductive tracts are unstriated and involuntary

Answer 1

The correct option is C

The muscles located in the inner walls of the alimentary canal are striated and involuntary

Smooth muscles are 'involuntary' and non-striated muscles as they cannot be controlled directly like that of skeletal muscles which are voluntary, controlled and possess striations. The, inner walls of alimentary canal are composed of non-striated and involuntary muscles. All other statements are correct.
