The system that encompasses nerves branching to every part of the body is known as what?

1. Central nervous system

2. Peripheral nervous system

3. Autonomic nervous system

4. Somatic system

The correct answer is: Peripheral nervous system

The correct answer is the peripheral nervous system. This system is responsible for connecting the central nervous system, which includes the brain and spinal cord, to the limbs and organs throughout the body. The peripheral nervous system serves as a communication network, transmitting signals between the central nervous system and the rest of the body, allowing for voluntary movements and involuntary processes. The peripheral nervous system is further divided into the somatic system, which controls voluntary muscle movements, and the autonomic system, which regulates involuntary body functions such as heart rate and digestion. Its extensive network of nerves branches out to every part of the body, making it essential for overall bodily function and response to stimuli. Understanding this distinction is critical in fields such as first aid and healthcare, as it clarifies how various bodily functions are coordinated and impacted by injuries or medical conditions.
