Question

Intercalated discs are present in____________

• A. Striated muscles
• B. Unstriated muscle
• C. Cardiac muscles
• D. All of the above

Answer 1

The correct option is C Cardiac muscles

Cardiac muscles consist of cylindrical, branched and uninucleate myocytes. Myocytes are interconnected by intercalated discs. Intercalated discs are cross-bands that separate the opposite ends of myocytes. Intercalated discs help to hold the adjacent cells together and transmit the force of contraction from cell to cell. These discs allow diffusion of ions across the cells due to which muscle impulses travel rapidly from cell to cell. Therefore, option C is correct.
