Which feedback stimulates your body to respond in the same direction as a stimulus positive or negative?

What hormone is responsible for the beginning stages of labor?

Progesterone. When the level of progesterone drops, it causes the uterus wall to begin contracting, which pushes the baby's head into the cervix, starting the positive feedback loop of contractions in labor.


Which hormones is regulated by a positive feedback mechanism?

Best example of positive feedback is the release of oxytocin during childbirth. Oxytocin is a reproductive hormone in females. Though it is also secreted in males, its function is yet unclear. Secretion of oxytocin occurs in response to nervous stimulation of the hypothalamus. It stimulates and enhances labor contractions. During the movement of the baby towards the birth canal, messages from pressure receptors within the cervix reach the brain to produce oxytocin. Released oxytocin travels to the uterus through the bloodstream and stimulates the uterine wall muscles to contract stronger. These contractions intensify gradually and increase until the baby comes out of the birth canal.Labor contractions are stopped when the stimulus to the pressure receptors ends and when oxytocin production stops in turn. Another means of oxytocin release is during lactation where the nipple sends impulses to the hypothalamus upon suckling, leading to contraction of the myoepithelial cells and expulsion of milk under positive feedback control.


How is the level of oxytocin controlled by a positive-feedback mechanism?

Oxytocin release is controlled by a positive-feedback mechanism during childbirth. When contractions of the uterus stimulate oxytocin release, this hormone further intensifies contractions, leading to more oxytocin release. This cycle continues until the baby is delivered.


Is Oxytocin release a positive or negative feedback control mechanism?

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.

The increasing labor contractions of childbirth are an example of?

positive feedback


Describing what is feedback system and differentiating between positive and negative feedback?

when a woman's contractions speed up during labor is negative or positive feedback


How might a person exhibit positive feedback communication?

Positive feedback increases the original stimulus. An example is labor contractions. The initial contraction signals the body to release hormones that increase the frequency and intensity of subsequent contractions.


Is contractions during childbirth positive or negative feedback?

Positive feedback.


The increasingly forceful labor contractions during childbirth are an example of?

The increasingly forceful labor contractions during childbirth are an example of the body's natural physiological response to help facilitate the delivery of the baby. These contractions serve to push the baby through the birth canal and out of the mother's body.


What is a positive feedback mechanism?

A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment


Are contractions in the uterus a process regulated by negative or positive feedback?

Uterine contractions are one of the few physiologic process regulated by positive feedback.


What is an example of a positive feedback to maintain homeostasis?

During childbirth, the hormone oxytocin is released in response to uterine contractions. Oxytocin further stimulates more contractions, leading to the eventual delivery of the baby, which helps maintain homeostasis by expelling the fetus from the mother's body.

What is a feed Back?

It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
