Choose the two different types of muscle.

a. Skeletal and nerves
b. Inner and outer
c. Voluntary and involuntary
d. Long and short

c. Voluntary and involuntary

d. Long and short

The two different types of muscle are:

c. Voluntary and involuntary.

The correct answer is c. Voluntary and involuntary.

To arrive at this answer, we need to understand the two different types of muscle based on their control.

Skeletal muscles are controlled voluntarily, meaning they are under our conscious control. These muscles enable us to move our body parts, such as our arms and legs, as well as perform activities like walking, running, and lifting weights.

On the other hand, involuntary muscles are not under conscious control. They work automatically and independently of our thoughts. These muscles regulate important bodily functions, such as digestion, heartbeat, and breathing. Examples of involuntary muscles include smooth muscles found in the walls of our internal organs and cardiac muscles found in the heart.

Therefore, the correct answer is c. Voluntary and involuntary muscles.
