The term for changes in the internal or external environment that cause a response is stimuli. Stimuli can be defined as any event or sensory input that causes an organism to respond in some way. In this context, stimuli can be things like temperature changes, sound, light, or chemicals that trigger a response in an organism. Nerves are the cells that transmit signals in the nervous system, and messages and signals are more general terms that can refer to any type of communication, including those between organisms, but they are not specific to the concept of causing a response in the presence of a change in the environment.
