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.

Answer:
The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6)
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
9 : 6 : 1
Answer:
A
Explanation:
Botulism and tetanus are both serious neurological infectious diseases in humans as well as animals. Botulism is caused by clostridium botulinum while tetanus is caused by clostridium tetani. Both organisms produce neurotoxins that act on nerves and eventually on muscles to cause respiratory failure.
The major difference between botulism and tetanus is that, in botulism, there is a characteristic descending flaccid paralysis. Signs and symptoms include; facial weakness, difficulty speaking, difficulty swallowing, drooling, shortness of breath and eventually respiratory paralysis.
Tetanus is characterized by spastic paralysis. Symptoms include; painful muscle contractions, fever, difficulty in breathing, difficulty in swallowing, and respiratory paralysis.
