The nervous system signaling is the process by which nerve cells, or neurons, communicate with each other and with other cells in the body. This communication occurs through electrical impulses and chemical signals called neurotransmitters. When a neuron is activated, it generates an electrical signal that travels along its axon to the synapse, where neurotransmitters are released to transmit the signal to the next neuron. This signaling is essential for various functions, including movement, sensation, and reflexes. The central nervous system (comprising the brain and spinal cord) and the peripheral nervous system (which connects the central nervous system to the rest of the body) work together to ensure that signals are sent and received efficiently, allowing for coordinated responses to stimuli.
