What are the 3 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 is external response?

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 an external stimulus.

Is food an external stimulus?

The digestive system can respond to external stimuli, such as the sight or smell of food, and cause physiological changes before the food ever enters the body.

Which is an external stimulus answers?

• Temperature (thermoreceptors)
• Pressure (mechanoreceptors)
• Light (photoreceptors)

What stimuli explain?

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 external stimulation?

External stimuli are factors outside of the body that are taken in by receptors and will lead to a response. Examples of external stimuli include temperature changes, vision, hearing, tasting, smelling, and even sunlight for plants.

What is external and example?

In general, external refers to anything outside of a location, object, or device. 2. External describes a hardware device that’s installed outside of the computer. For example, a printer (shown in picture) is an external device because it connects to the back of the computer and is outside the case.

What is external stimuli in cell?

Cells respond to external stimuli via receptors located on the cell surfaces. These receptors are sensing components, monitoring stimuli and responding to all changes in the surrounding environment by relaying a signal targeting a control centre. After that, the signal is further processed and a response is given.

Is temperature an external stimulus?

External stimuli come from outside an organism and influence the organism’s behavior. Temperature, sound, light, and other organisms act as external stimuli and cause different responses in organisms.

Is stress an external stimulus?

Specialists now define stress as any external stimulus that threatens homeostasis — the normal equilibrium of body function. Stress also can be induced by the belief that homeostasis might soon be disrupted.

Is the sun an external stimulus?

The hot sun is an external stimulus.

What is an example of external stimuli in a plant?

The response of an organism, usually a plant, to an environmental stimulus is called a tropism. Some common plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.

What is an example of a response to an internal stimulus?

Internal stimuli are changes, experiences, or feelings that occur within someone. Examples include hunger, thirst, and emotional states. Internal stimuli are often contrasted with external stimuli, which are changes or experiences that occur outside.

Which is an example of an animal responding to an external stimulus?

Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather (stimulus) some animals will hibernate.
