Question

Write two difference between the muscles present in the heart and ailmentary Canal. Also draw labelled diagram of these two kinds of muscles

Answer 1

The muscles present in the heart are known as cardiac muscles whereas muscles of the alimentary canal  are smooth muscles. Cardiac muscles are striated, but smooth muscles are non-striated.

• Each cardiac muscle cell has one or more nuclei, but the smooth muscle cells are single nucleated.

• Cardiac muscle cells are often branched, but smooth cells are non branched.

• Smooth muscle cells are fusiform-shaped, but cardiac muscle cells are long and cylindrical.
