Which of the following statements wrongly represents the nature of smooth muscle?

Options

A. They are involuntary muscles
B. Communication among the cells is performed by intercalated discs
C. These muscles are present in the wall of blood vessels
D. These muscles have no striations

Answer

B

Explanation

It is incorrect because intercalated discs are found only in cardiac muscle tissue. Communication among the cells is performed by intercalated discs in cardiac muscle. Intercalated discs are absent in smooth muscle.
• Smooth muscle fibres are non-striated and involuntary in nature and are present in the wall of blood vessels, uterus, gall bladder, alimentary canal etc.
