negative feedback
Oxytocin release is a positive feedback control mechanism. This means that an initial stimulus triggers the release of oxytocin, which then promotes further release of oxytocin, amplifying the response until a specific outcome is achieved, such as uterine contractions during childbirth.
Yes, oxytocin release is an example of a positive feedback control mechanism. In response to stimuli such as childbirth or breastfeeding, oxytocin is released, which leads to stronger contractions in the uterus or milk let-down reflex, further stimulating more oxytocin release. This cycle reinforces and amplifies the initial stimulus.

feedback inhibition. Feedback inhibition is a regulatory mechanism where the end product of a biosynthetic pathway inhibits the activity of the enzyme catalyzing the initial step, thereby regulating the overall rate of the pathway.
A negative feedback loop works to counteract changes in a variable, promoting stability within a system. When an initial change occurs, the negative feedback mechanism detects this deviation and triggers responses that reduce or negate the change. For example, if a body temperature rises, mechanisms like sweating are activated to lower it back to the set point. Thus, the negative feedback loop effectively dampens the initial change, restoring equilibrium.
positive feedback
Exaggerating the stimulus is also seen as amplifying the stimulus. This is seen in outer ear hair cells.The mechanism you refer to is probably a positive feedback mechanism: more of the stimulus causes more of the stimulus. This is in contrast to a negative feedback mechanism, whereby more stimulus results in processes that strive to attenuate (lessen) that stimulus.
exagerrates the stimulus
This process is known as negative feedback. Negative feedback works to maintain homeostasis by reversing the direction of the initial change in a stimulus, helping to stabilize and regulate physiological functions within the body. It is a key mechanism in maintaining balance and stability in biological systems.
Oxytocin release is a positive feedback control mechanism. This means that an initial stimulus triggers the release of oxytocin, which then promotes further release of oxytocin, amplifying the response until a specific outcome is achieved, such as uterine contractions during childbirth.
Yes
A negative feedback would be if the planet heats up, the glaciers will melt, lowering the albedo effect of the snow, and in turn causing the planet to heat up more That is positive feedback, not negative. Positive feedback enhances the initial stimulus, negative feedback reverses the initial stimulus. The planet starts by heating up, then heats up even more, which is positive feedback.

positive feedback.
Yes, oxytocin release is an example of a positive feedback control mechanism. In response to stimuli such as childbirth or breastfeeding, oxytocin is released, which leads to stronger contractions in the uterus or milk let-down reflex, further stimulating more oxytocin release. This cycle reinforces and amplifies the initial stimulus.
The initial learning of the stimulus-response link is known as acquisition. During this stage, an individual learns to associate a specific stimulus with a particular response through repeated exposure and practice. This process may involve reinforcement and feedback to strengthen the connection between the stimulus and the desired response.
