To solve this problem, we need to analyze the given statements about smooth muscle:$\newline \bullet$Option 1: These muscles have no striations.$\newline$ - Smooth muscles are non-striated, meaning they do not have the banded appearance seen in skeletal and cardiac muscles.$\newline$ - This statement is correct.$\newline \bullet$Option 2: They are involuntary muscles.$\newline$ - Smooth muscles are controlled by the autonomic nervous system and are not under voluntary control.$\newline$ - This statement is correct.$\newline \bullet$Option 3: Communication among the cells is performed by intercalated discs.$\newline$ - Intercalated discs are specialized structures found in cardiac muscle, not in smooth muscle.$\newline$ - Smooth muscle cells communicate through gap junctions, not intercalated discs.$\newline$ - This statement is incorrect and wrongly represents the nature of smooth muscle.$\newline \bullet$Option 4: These muscles are present in the wall of blood vessels.$\newline$ - Smooth muscles are indeed found in the walls of blood vessels, where they help regulate blood flow and pressure.$\newline$ - This statement is correct.$\newline$Therefore, the statement that wrongly represents the nature of smooth muscle is Option 3.
