Which term describes tissue controlled at will with impulses from the brain, enabling movement?

• A. Voluntary
• B. Cardiac
• C. Involuntary
• D. Smooth

Answer: (A)

Movement comes from skeletal muscle tissue, which you can control at will. The brain sends conscious motor commands through the nervous system to the muscles, triggering contraction to produce deliberate movements. This ability to be controlled by mind and to move on purpose is what “voluntary” describes. In contrast, cardiac muscle (the heart) and smooth muscle (walls of organs and vessels) operate automatically under the autonomic nervous system, so they’re involuntary. So the term that fits tissue controlled at will with brain impulses enabling movement is voluntary.
