What system controls both voluntary and involuntary body activities and supports higher mental functions?

1. Skeletal system

2. Central nervous system

3. Endocrine system

4. Muscular system

The correct answer is: Central nervous system

The central nervous system is the correct answer because it plays a key role in coordinating both voluntary movements, such as walking or writing, and involuntary functions, like breathing and heart rate regulation. It consists of the brain and spinal cord, which process information and transmit signals throughout the body. Additionally, the central nervous system is responsible for higher mental functions such as thinking, learning, memory, and emotional responses, making it essential for the overall functioning of the human body. In contrast, the skeletal system primarily provides support and structure to the body, while the muscular system focuses on facilitating movement through muscle contractions. The endocrine system regulates various bodily functions through hormones but does not directly coordinate voluntary and involuntary activities like the central nervous system does.
