Detailed explanation-1: -In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism’s internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability).
Detailed explanation-2: -Environmental stimuli were defined as ambient, architectural or interior design features that are intended purely to provide a stimulus and that influence patients through mediation by psychological processes.
Detailed explanation-3: -They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
