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.
The oxyhemoglobin dissociation curve represents a negative feedback mechanism?
A negative feedback mechanism is a system to return a disruption in homeostasis back to homeostasis.A positive feedback mechanism is a system to reinforce or perpetuate a disruption in homeostasis.The oxyhemoglobin dissociation curve represents the Partial pressure in oxygen that will be saturated in the amount of hemoglobin.This curve represents a positive feedback because the binding of Oxygen to hemoglobin facilitates more binding of oxygen to hemoglobin (you can see this in the rapid rise in saturation from 10-40 mm Hg) until it reaches 60 mm Hg where it is somewhat completely saturated
Control mechanism that lower blood pressure in response to a rapid rise in blood pressure are called?
negative feed back
Prominent projection at back of skull?
Is called the External Occipital Protuberance and its function is simply an attachment for the occipitalis muscle.
What do automatic external defibrillators do?
When a heart is said to be in fibrillation it means that it has lost its rhythm and is basically quivering. Automatic external defibrillators (AED) provide an electric shock to the heart which has been known to get it back to its usual rhythm.
How is oxytocin an example of a hormone that is under positive regulaton?
Yes it is an example. There a positive feed back mechanism take place
What is the difference between a positive and negative feedback mechanism?
one goes foreward, one goes back, pretty self-explanatry isnt it, idiot
How internal customer can affect the external customer?
The internal customers can affect the external customers because they act as the ad-promoters and help by giving more information about the quality and services of your business and products. Thus, the external customers get the feed back and if it is positive they are attracted to your products and services.

Can you use an external antenna for the tom tom 720?
yes, there is an external connector on the back of the device.
Can you wire a external and an internal ground together on a drier?
The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.
How do you recline a stratolounger couch by Stratford Co that has no visible mechanism?
There are a few ways it may recline. Some have a "hidden" release mechanism located between the seat cushion and the arm of the sofa. Some have a "push back" mechanism where you just push and lean back.

What does the control center do in the negative feed back cycle?
That is very hi tech question! There should be no role of any control center in negative feed back mechanism. Both should regulate each other. But then the control center is required to do the up regulation or down regulation in this negative feed back mechanism. For example your blood pressure may get set at higher level in case of chronic psychological stress. Such stress is so common now a days.
How does an electric batterys work?
In the simplest terms: controlled electrochemical corrosion, which causes the transfer of electrons through the electrolyte from the positive plate to the negative plate. When connected to an external load the excess electrons on the negative plate can then flow through the load (thereby doing work) and back to the positive plate.
Your trunk will not lock it you shut it it will pop back open?
Try lubricating lock mechanism Try adjusting mechansim Replace locking mechanism
