What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.

Is thermoregulation in humans regulated through positive or negative feedback systems?
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
What kind of feedback mechanism is it when it causes the initial stimulus to decline?
negative feedback
What is the difference between feedback negative feedback a negative feedback response a negative feedback mechanism and a negative feed back loop?
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
Negative feed back on homeostasis?
Homeostasis is the way that the body to has a tendency to stabilize itsÕ self. Some people think of homeostasis as a negative thing in relation to oneÕs weight or for medical reasons that their body has naturally acclimated to a state they wish was different.
Is reflex a form of a negative feedback response?
Reflex is not necessarily a form of negative feedback response. Reflexes are quick, involuntary responses to stimuli, while negative feedback is a regulatory mechanism that helps maintain homeostasis by reducing the effects of any deviation from an ideal set point. Reflexes can be part of negative feedback loops, but not all reflexes are negative feedback responses.

What is the integrating center for the negative feedback loop that regulates body temp?
There are two main components: 1- Positive feedback- The inciting event is heat radiation stimulating anterior hypothalamus nerves that cause stimulation. These then stimulate inhibiting nerves which cause hyperpolarization of sympathetic nerve systems 2- Negative feedback- The inhibition causes a decrease in sympathetic tone causing vasodilation of the vasculature, that results in heat loss. The returning temperature of blood decreases, resulting in less transfer of heat radiation, and thus homeostasis of body temp. The opposite for decrease heat radiation. Stimulus to cold: 1- Positive feedback- Decrease in transfer of heat energy causes less depolarization of nerves in the hypothalamus, thus less stimulation of inhibitory nerve cells regulating sympathetic tone. 2- Negative feedback- Less positive inhibition causes increased activity of sympathetic nerve ending, thereby increasing vasculature tone, and thus vasoconstriction, and decreased body heat loss. Thus, the global negative feedback is a complex interplay of several negative and positive loops, that account for: increase heat radiation->increased vasodilation through inhibition of sympathetic tone. Decreased heat radiation->decreased vasodilation (vasoconstriction) through decreased inhibition of sympathetic tone. To answer the question more simply: anterior hypothalamus (inhibitory neurons by positive effect from heat sensing neurons) and sympathetic nervous system
How does negative feedback help regulate your internal body temperature?
it helps your internal body temperature alot. The negative feedback heats the inside of you so you don't freeze. Its pretty simple when you think about it. Negative feedback is like a thermostat.
When body temperature rises a center in the brain initiates physiological changes to decrease the body temperature is an example of negative feedback or positive feedback?
This is an example of negative feedback because the body is working to reverse the initial change in order to restore homeostasis. When the body temperature rises, the brain triggers responses such as sweating and vasodilation to help cool down the body and bring the temperature back to the normal range.
What is an example of a negative feedback in human body?
example of negative feedback example of negative feedback
Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is negative feedback of a closed loop system?
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
What kind of feedback is used in emitter follower?
emitter follower is a type of negative feedback ,
What kind of feedback mechanism is it when it causes the initial stimulus to decline?
negative feedback
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
What is the difference between feedback negative feedback a negative feedback response a negative feedback mechanism and a negative feed back loop?
