Is Oxytocin release a positive or negative feedback control mechanism?
positive
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
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.
Why is positive feedback helpful in blood clotting but unsuitable for the regulation of body temperature?
Positive feedback accelerates the clotting process, but temperature would rise out of control.
Does the endocrine system often run on negative feed back?
Endocrine system usually uses the negative feed back mechanism. So suppose when thyroid stimulating hormone is released, then thyroid hormones are released. They reduce the secretion of thyroid stimulating hormone. This is how the secretions of the hormones is regulated. In positive feed back mechanism, the level of both the hormones will raise and will create lot of problems.
Is Oxytocin release a positive or negative feedback control mechanism?
positive
Is oxytocin an adenohypophyseal secretion?
no, it's release is the effect of a positive control feedback mechanism
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor

Feedforward feedback control?
Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits
What are 5 examples for positive feedback control mechanism?
1) blood clotting 2) release of oxytocin during child birth 3) protein digestion- presence of partially digested protein triggers the secretion of HCl and pepsin 4) In nerves, a threshold electric potential triggers the generation of much larger action potential
Do positive feedback makes homeostasis get out of control?
yes...
Why is a cycle of events in one step control or affect a previous step?
feedback mechanism
What is a control mechanism that controls an earlier reaction?
positive ffedback
Why is positive feedback helpful in blood clotting but unsuitable for the regulation of body temperature?
Positive feedback accelerates the clotting process, but temperature would rise out of control.
What is the endocrine definition of self-regulating?
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
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.
