Arkansas Esthetician Practice Exam

What kind of muscles respond automatically to control various body functions?

1. Striated

2. Voluntary

3. Non-striated

4. Skeletal

The correct answer is: Non-striated

Non-striated muscles, also known as smooth muscles, are involuntary muscles that respond automatically to control various body functions such as digestion, blood flow, and breathing. Striated muscles, also known as skeletal or voluntary muscles, are controlled by conscious effort and are responsible for movements of the body. Voluntary muscles, as the name suggests, are controlled voluntarily, but they are also striated. Skeletal muscles are a type of striated muscle responsible for the movement of bones and joints in the body. Therefore, C is the correct answer as it specifically mentions the type of muscle that responds automatically, while the other options refer to voluntary or skeletal muscles which are not automatic in their response.
