Final answer:
The answer to the question is 'nerves,' which are part of the peripheral nervous system. The central nervous system consists of the brain and spinal cord, while the peripheral nervous system connects the CNS to the rest of the body. Nerves play a vital role in transmitting signals between the CNS and the body.
Explanation:
Understanding the Peripheral Nervous System
The question asks which of the following is part of the peripheral nervous system:
- Brain
- Kidneys
- Nerves
- Spinal cord
To answer this question, it's important to recognize that the nervous system is divided into two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of nerves outside of the CNS. Therefore, among the options provided, nerves are part of the PNS.
The PNS connects the CNS to the rest of the body and plays a crucial role in transmitting sensory and motor signals. For example, when you touch something hot, sensory nerves in your skin send a signal to your brain through the PNS, and your brain then sends a signal back through the PNS to move your hand away.
