What is the main function of the nervous system?

• A. To create energy for cellular activities
• B. To control and coordinate body activities
• C. To facilitate gas exchange in the lungs
• D. To store and release minerals

Answer: (B)

The main function of the nervous system is to control and coordinate body activities. This system is integral to how organisms interact with their environment and maintain homeostasis. It processes sensory information, sends signals to muscles and glands, and orchestrates the complex network of bodily functions. This includes both voluntary actions, like moving a limb, and involuntary responses, such as reflexes, along with regulating internal processes like heart rate and digestion through the autonomic nervous system. Understanding the nervous system's role highlights its importance in integrating various bodily functions, allowing for the rapid response to changes in both internal and external conditions. This dynamic capability is essential for survival, as it enables an organism to react promptly to potential threats, pursue nourishment, and carry out complex behaviors necessary for development and reproduction.
