The human nervous system is a complex network that enables communication between different parts of the body. It consists of two main components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of all the nerves that branch out from the CNS. The nervous system plays a vital role in controlling bodily functions, processing sensory information, and facilitating movement.
Neurons are the fundamental units of the nervous system, responsible for transmitting signals throughout the body. When a neuron is stimulated, it generates an electrical impulse that travels down its axon to the synapse, where it can communicate with other neurons through neurotransmitters.
