In physiology, a stimulus is a detectable change in the internal or external environment. When a stimulus is applied to a sensory receptor, it elicits or influences a reflex via stimulus transduction. A stimulus is often the first component of a homeostatic control system. When a sensory nerve and a motor nerve communicate with each other, it is called a nerve stimulus. Image File history File links This is a lossless scalable vector image. ...

In a sensory system, a sensory receptor is a structure that recognizes a stimulus in the internal or external environment of an organism. ... A reflex action is an automatic (involuntary) neuromuscular action elicited by a defined stimulus. ... In physiology, transduction is the conversion of a stimulus from one form to another. ... Homeostasis is the property of either an open system or a closed system, especially a living organism, to regulate its internal environment to maintain a stable, constant condition. ...

In Simple words w can define the stimulus as "A stimulus is a function which generates some action" Stimulation is the irritating action of various agents (stimuli) on muscles, nerves, or a sensory end organ, by which activity is evoked; especially, the nervous impulse produced by various agents on nerves, or a sensory end organ, by which the part connected with the nerve is thrown into a state...

If a mechanical stimulus is applied to a mechanoreceptor, a generator potential is recorded such that the amplitude of the generator potential is a function of the amount of deformation of the receptor surface.
Stimulus C is applied at another place on the receptor at the same time as A in the second set of records.
Complementary to the principle of the adequate stimulus is a notion formulated by Johannes Müller.
