What is the main role of the nervous system?

• A. Controls movements and reflexes
• B. Supports and protects organs
• C. Regulates body temperature
• D. Stores fat for energy

Answer: (A)

The main role of the nervous system is to control movements and reflexes. This complex network of neurons is responsible for transmitting signals throughout the body, allowing for coordination and communication between different body parts. It processes sensory information, enabling the body to respond to stimuli with appropriate motor responses. This includes both voluntary actions, like walking or talking, and involuntary reflex actions, such as pulling a hand away from a hot surface. While the other options describe important functions of different body systems, they do not pertain to the primary function of the nervous system. For instance, supporting and protecting organs relates to the skeletal and muscular systems, regulating body temperature is primarily a function of the integumentary and endocrine systems, and storing fat for energy is a role of adipose tissue within the endocrine and metabolic systems. Thus, the correct answer reflects the essential role of the nervous system in controlling and coordinating the body's movements and reactions.
