Neural control of gfr is mediated by ________ that innervate ________ receptors on vascular smooth muscle causing ________
storchak [24]

Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.

<h3>How is GFR regulated?</h3>
  • The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
  • GFR is the sum total of filtration rates of all the working nephrons in the kidney.
  • Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
  • In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
  • Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
  • Alpha receptors are more abundant on afferent arterioles.
  • This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
  • This decreases blood flow to glomerulus, leading to decrease in GFR.

How do divison plz give me a problem and help me on it..
JulsSmile [24]
Division is basically a mathematical function that can be used to take parts of other numbers. 

In division, there are two main things you have to remember, the dividend, or the number that is being divided into some part. The part is also called the divisor, or the number that is dividing the dividend.
Here is an example:
200 ÷ 100 => 100 is the divisor and 200 is the dividend
Here is how you solve it:
200 ÷ 100 = ?
Multiplication: what times 100 is 200? The answer is 2.
200 ÷ 100 = 2

Hope this helps and have a phenomenal day!
