How do nerves act as a link between the nervous system and other parts of the body?

Nerves serve as conduits that transmit signals between the nervous system and various parts of the body. They carry sensory information from peripheral receptors to the central nervous system (CNS) and relay motor commands from the CNS to muscles and organs. This communication enables the body to respond to internal and external stimuli, coordinating actions and maintaining homeostasis. Additionally, the autonomic nervous system regulates involuntary functions, further connecting the nervous system to bodily processes.
