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.) as a result of a stimulus.
A Look at Stimuli
As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.
Stimulus is something that causes a reaction, especially interest, excitement or energy. An example of stimulus is a shiny object for a baby. An example of stimulus is an influx of cash into the economy that is designed to help the economy to gain momentum or energy.
The definition of response is a reaction after something is done. An example of response is how someone reacts to an ink blot on a card. Response is defined as an answer to a question. An example of response is what happens after the question during a question and answer discussion.
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. Chemical substances produced by the body that excite pain receptors include bradykinin, serotonin, and histamine.
The organism responds to the stimuli by means of a number of effectors, such as muscles and glands. Energy is generally used in the process. Organisms change their behavior in response to changes in the surrounding environment. For example, an organism may move in response to its environment.
Broadly, sensory receptors respond to one of four primary stimuli:
Chemicals (chemoreceptors)Temperature (thermoreceptors)Pressure (mechanoreceptors)Light (photoreceptors)
TYPES OF RESPONSE OR IRRITABILITY, TROPHIC MOVEMENT, TYPES OF TAXIS RESPONSE, NASTISM RESPONSE AND ROLES OF AUXINS IN GROWTH MOVEMENT. One of the characteristics of a living thing is responding to stimuli. All living thing are capable of responding to internal and external stimuli.
1 : an act of responding. 2 : something constituting a reply or a reaction: such as. a : a verse, phrase, or word sung or said by the people or choir after or in reply to the officiant in a liturgical service. b : the activity or inhibition of previous activity of an organism or any of its parts resulting from
In the context of science, a stimulus is anything that makes an organism or a part of an organism react in some way. For example, for most plants, sunlight acts as a stimulus that causes (stimulates) them to grow or move toward it.
