Question

Which of the following muscles control the internal movements?

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

Answer 1

Answer: (D)

Both A and B

The internal movements are performed by the involuntary muscles. The involuntary muscles function on their own and cannot be controlled willingly. The cardiac muscles are the involuntary muscles which are responsible for the pumping of the heart. The heart pumps and supplies the oxygenated blood to the different tissues in the body. The smooth muscles are responsible for carrying out peristalsis in the tube like structures of the alimentary canal. This movement helps in propelling the food in the forward direction. Both these muscles are of the involuntary type.

Thus, the correct answer is option D.
