Physiology

Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided between plant physiology and animal and all living things physiology but the principles of physiology are universal, no matter what particular organism is being studied....
, a stimulus (plural stimuli) is a detectable change in the internal or external environment. When a stimulus is applied to a sensory receptor
Sensory receptor

In a sensory system, a sensory receptor is a sensory nerve ending that recognizes a stimulus in the internal or external environment of an organism....
, it elicits or influences a reflex
Reflex action

A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a Stimulus . In most contexts, in particular those involving humans, reflex actions are mediated via the reflex arc; this is not always true in other animals, nor does it apply to casual uses of the term 'reflex'....
 via stimulus transduction
Transduction (physiology)

In physiology, transduction is the conversion of a stimulus from one form to another.Transduction in the nervous system typically refers to synapse events wherein an electricity signal, known as an action potential, is converted into a chemical one via the release of neurotransmitters....
. A stimulus is often the first component of a homeostatic control system
Homeostasis

Homeostasis is the property of a system, either open system or closed system, that regulates its internal environment and tends to maintain a stable, constant condition....
. When a sensory nerve and a motor nerve communicate with each other, it is called a nerve stimulus.

Any of your five senses will accommodate to a particular stimulus.

Any of your five senses will accommodate to a particular stimulus. The stimulus–response model describes how statistical units such as receptor cells response to their effective stimulus.
