Question

Which of the following muscles are striated and branched?

• A. Skeletal muscles
• B. Smooth muscles
• C. Cardiac muscles
• D. Both A and C

Answer 1

Answer: (C)

Cardiac muscles

The cardiac muscles (heart muscles) are involuntary striated muscles that are found in the walls of the heart. The heart is a pumping organ that needs to work tirelessly. To ensure this pumping efficiently, the cardiac muscle cells are bundled together giving the muscle a branched appearance. These bundled cells thus allow quick transmission of electrical signals which aid in efficient contraction and relaxation of the cardiac muscles. This in turn helps in the efficient pumping of the heart.

So, the correct answer is option C.
