Electric signals interpreted by your brain.
The term used to describe what causes organisms to react to their environment is "stimulus." A stimulus can be any change in the environment that elicits a response from an organism, such as light, temperature, or sound. Organisms respond to these stimuli through various behaviors or physiological changes to adapt and survive.
stimulus
They react in same way most animals do. They respond to any stimulus. The stimulus can be touch, smell, sight etc... Blue Whales are likely to not to respond to same things as humans such as touch but still react to stimulus. An example being swimming deeper when a boat is near by.
stimulus. (plural, stimuli)
Homeostasis is the body's ability to maintain a stable internal environment, such as temperature and pH, through self-regulating mechanisms. Stimulus, on the other hand, is any event or signal in the external environment that triggers a response from an organism to maintain homeostasis. In essence, homeostasis is the state of balance, while stimulus is the external factor that disrupts that balance and prompts a response.
Practically anything can be a stimulus, so organisms can respond to them in just about any way. The definition of 'stimulus' and 'response' are a little paradoxical in this context in that a stimulus is anything that provokes a response and a response is anything done to react to a stimulus. Perhaps some examples will make it clearer: if a predator grasps a lizard's tail (stimulus) it will detach the tail and escape (response). If the weather is excessively hot (stimulus), a plant will close the stomata in its leaves to conserve water (response). If a laboratory mouse notices a new object in its cage (stimulus), it will go investigate it (response).
A stimulus is basically considered to be a detectable change inside or outside the body. If you sit quietly for a while, and then a loud noise goes off, that is a change from the quiet state, and therefore considered a stimulus. You most likely will jump.But if you get used to that loud noise, then you have adapted to it and it no longer triggers a response, it is no longer a stimulus; it is not changing.Basically something which urges a response is called a stimulus.
The cardiac muscle is incapable of reacting to any stimulus before approximately in the middle of phase 3. It will not react to a normal cardiac stimulus before phase 4.
Spider behavior appears to be TROPIC... that is, they react in a programmed fashion to any given stimulus, without thinking or reasoning.While they have evolved to avoid stimulus that is indicative of danger... it is a matter of conjecture whether a tropic reaction to stimulus could qualify as an emotion such as fear.
The name given to any factor that causes sensory receptors to begin to function is a stimulus. This can include physical stimuli such as light, sound, touch, taste, and smell, as well as internal stimuli such as changes in temperature or pressure.
Gold is nontoxic. It doesn't react to any organs in the body. :)
A kinesthetic stimulus refers to any input that activates the body's sense of movement and position, primarily through muscle and joint sensations. It plays a crucial role in proprioception, which is the awareness of body parts' positions and movements. This type of stimulus is essential for activities that involve coordination, balance, and motor skills, helping individuals understand their body's spatial orientation and movement through physical interactions.
