Synonyms: physiological response to stimulus. Definition: Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.)
What is a response to a stimuli called?
Explanation: In physiology, a stimulus (plural stimuli or stimuluses) 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 respond to external stimuli is called sensitivity .
What is an example of a response to a stimulus?
Response: how the organism reacts to a stimulus and results in a change in behavior. (It is a fancy way of saying “effect”.) Example: Getting a drink when you are thirsty .
What is response to stimuli easy definition?
A stimulus causes an action or response , like the ringing of your alarm clock if you didn’t sleep through it. Stimulus is a word often used in biology — something that causes a reaction in an organ or cell, for example. ... For more than one stimulus, use stimuli, not stimuluses.
What can respond to stimuli?

What is a stimulus in behavior?
Stimuli are events in the environment that influence behavior . A single stimulus can serve many different functions. Listed below are several functions that a stimulus can serve. ... An observing response is sometimes necessary for presentation of the discriminative stimulus/stimuli.
What are the two types of stimuli give examples?
There are two types of stimuli that affect the body: external and internal . External stimuli are changes to conditions outside of the body, or in general, information from outside the body that our senses detect. For example, our bodies respond to changes in light and temperature and to sources of danger.
What are the 5 types of stimuli?
Our brains commonly receive sensory stimuli from our visual, auditory, olfactory, gustatory, and somatosensory systems .
What are the types of stimuli?
excited by three types of stimuli— mechanical, thermal, and chemical ; some endings respond primarily to one type of stimulation, whereas other endings can detect all types.
What are the two types of stimulus?
Types of Stimuli. There are two main types of stimulus – the external stimulus and the internal stimulus .
What is stimulus give example?
A stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine . An example of internal stimuli is your vital signs changing due to a change in the body.
What is the difference between stimuli and response?
A change in the environment is the stimulus; the reaction of the organism to it is the response.

Does a car respond to stimuli?
A driver is expected to respond by accelerating when faced with positive stimulus , to drive at a constant speed when the stimulus is too small to detect, and decelerate when faced with a negative stimulus. The combination of state of the stimulus and three possible responses is shown in Table 3, Table 4.
How does the brain respond to stimuli?
Receptors are groups of specialised cells. 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.
Do rocks respond to stimuli?
Stimuli: Anything from the environment that causes some sort of reaction, such as temperature, light, sound, and other factors that cause living things to respond. Nonliving objects (rocks for instance) do not respond to stimuli!
