When any part of an organism or of man’s sensory organs is stimulated, a reaction or a response will result. A response is the behavior that is manifested by a living organism which is the result of an external or internal stimulus.
What is stimulus in biology?
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).
What is stimulus Short answer?
In general, a stimulus is something that provokes or causes an action or response, as in Failing that test was the stimulus I needed to start studying harder. The plural of stimulus is stimuli. Its verb form is stimulate, which typically means to spur into action or to invigorate.
What is stimulus class 11 biology?
A detectable change in the chemical or physical structure of an organism’s external or internal environment is called a stimulus. Sensitivity is the ability of an organ or organism to detect external stimuli, so that an appropriate reaction can be produced.
What is a stimulus example?
Stimulus: any change in an organism’s environment that causes the organism to react. It is a fancy way of saying “cause”. Example: An animal is cold so it moves into the sun.
What is stimuli in biology examples?
What is a stimulus? In biology, we can define stimulus as the “detectable change (physical or chemical) in the environment of an organism that results in some functional activity”. For example, sunlight acts as a stimulus for plants that helps them grow or move towards it.
What is difference between stimulus and response?
The main difference between stimulus and response is that a stimulus is an event or condition which initiates a response whereas response is the organism’s reaction to a stimulus.
What is the difference between stimulus and impulse?
(a) Stimulus :Any change in the environment that usually results in change in the activity of the body. Impulse :A wave of electrical disturbance that runs through the nerves.
What is stimulus used for?
Stimulus checks are payments sent by the government to taxpayers to boost their spending power and spur economic activity. Stimulus checks are either mailed to taxpayers, deposited into their bank accounts, or applied as tax credits to lower their tax bills.
What is the best example of a stimulus class?
What is the best example of a stimulus class? The best example of a stimulus class is a toothbrush, toothpaste, mouthwash, & a cup of water because all items share the common attribute of being used to clean teeth.
What is a type of stimulus?
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 is an example of a stimulus and a response?
Example of a stimulus and a response: If you accidentally touch a hot object, you automatically withdraw your hand. The heat of the hot object is the stimulus and you, withdrawing your hand is the response to the stimulus.
What is stimulus in nervous system?
A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.
Which comes first stimulus or response?
A change in the environment is the stimulus; the reaction of the organism to it is the response.
What is the differences between response and stimulus provide two examples?
An example is the feeling of sadness and loneliness when a loved one dies. Summary: 1. A stimulus is any agent, condition, action, or activity which arouses a positive or negative reaction while a response is the resulting reaction towards the stimulus.
When was the first stimulus?

What is the stimulus in?
Stimulus is an event or any change in the external environment that evokes a specific functional reaction in an organ or tissue. stimulus can be internal or external. Sense organs, such as the ear, and sensory receptors, such as those in the skin, are sensitive to external stimuli such as sound and touch.
What is stimulus Class 6 short answer?
Answer: The changes in the surrounding to which living things respond are called stimuli.
What are the three types of stimulus classes?
There are three types of stimulus classes: formal, temporal and functional.
What are the 4 types of stimuli?
- Chemicals (chemoreceptors)
- Temperature (thermoreceptors)
- Pressure (mechanoreceptors)
- Light (photoreceptors)
What is nervous system class 10?
Nervous system is the organ system present in the animals to control and coordinate different activities of the body. Nervous system comprises of the brain, the spinal cord, and a huge network of nerves that are spread throughout the body.
Why do we respond to stimulus?
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.
Why does the body 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.
What is stimulus situation?
all the components of an occurrence or experience that, taken as a whole, comprise a stimulus to which an organism responds. The term is used to highlight the complexity of behavior-arousing events that are unitary patterns comprising many elements (e.g., a concert, an athletic competition).
