Question

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

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

Answer 1

Answer: (D)

Communication among the cells is performed by intercalated discs

Answer 2

The statement that wrongly represents the nature of smooth muscle is "Communication among the cells is performed by intercalated discs." This statement is incorrect because intercalated discs are a feature of striated muscle, specifically cardiac muscle. Smooth muscle lacks intercalated discs, which are primarily found in the heart's cardiac muscle cells. Smooth muscle cells communicate via gap junctions and other mechanisms, but not through intercalated discs.

So, the correct option is (D): Communication among the cells is performed by intercalated discs.
