The process of labor is induced by the release of the hormone Oxytocin from the pituitary gland. Oxytocin causes smooth muscle contraction associated with the uterus. Uterine contraction in turn causes the release of more Oxytocin from the pituitary, which causes more contraction. this represents a positive feedback loop of increasing amounts of Oxytocin and uterine contraction. Contractions of the uterus of course result in the movement of the fetus out of the birth canal (leaving the uterus, passing through the cervix, and out through the vaginal opening.
What else can I help you with?
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
When does feedback occur?
Feedback occurs when a response or reaction is provided to a particular action, behavior, or output. It is typically given after an event has occurred in order to provide information on performance, behavior, or outcomes. Feedback can be used to reinforce positive behaviors or make corrections for improvement.
How does negative feedback mechanism and positive feedback differ?
A negative feedback will stabilize an amplifiers positive feed back will force the amplifier to either saturated state. this will hold true for a system too. A more general answer follows. 1. Feedback: Getting information about what just happened and responding to it. 2. Negative Feedback: The response lessens the output. 3. Positive Feedback: The response increases the output.
What is it called that changes a cause of response?
The phenomenon you are referring to is called feedback. Feedback occurs when the output of a system or process is used as input to modify the operation of the system in order to achieve a desired result. It can be either positive (amplifying the original input) or negative (reducing the original input).
What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
When bodily changes are detected responses are activated that reverse the change restoring stability and preserving normal body function This occurs during what feedback?
It is NEGATIVE FEEDBACK.

What is type of feedback in which a given action promotes more of the same?
The type of feedback that promotes more of the same action is positive feedback. It occurs when the result or outcome of an action increases the likelihood of that action being repeated or continued. Positive feedback reinforces and encourages the behavior or action that produced it.
Body regulation occurs at 3 levels.localneuralhormonal.in many cases the same result occurs but through a different mechanism.why does this happen and what are some exapmles of other body regulations.?
Negative feedback, positive feedback, and neural control.
Why is positive feedback more likely than negative feedback to disturb homeostasis?
Positive feedback amplifies a response or process, leading to an increasingly significant deviation from a set point, which can disrupt homeostasis. For example, during childbirth, contractions intensify until delivery occurs, pushing the system further away from its initial state. In contrast, negative feedback mechanisms work to counteract changes and restore balance, promoting stability within biological systems. Therefore, while positive feedback can be essential in certain processes, it poses a greater risk of destabilizing homeostasis.
What is a positive interaction that occurs during play time between carer and baby?

What are four different effects of feedback on the function of an amplifier?
1. Negative feedback can increase linearity at the expense of losing gain. 2. & 3. Positive feedback can result in large increases in gain until the increases becomes so large that oscillation occurs. 4. Positive or negative feedback at one frequency can result in enhanced or decreased response to that frequency.
What is the word used to describe the physical change that occurs during adolescences?
Puberty.

When a deviation from a normal value occurs the response is to make the deviation even greater is this a negative feedback?
No, this is not a negative feedback response. In negative feedback, the system works to counteract the deviation and return to a normal value. Instead, making the deviation greater would indicate a positive feedback mechanism, where the response amplifies the initial change rather than correcting it.
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.
