ollegr [7]

Answer:

Fibrous

Explanation:

Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.

For example the fibrous proteins involved in horns, hair and nails is alpha-keratin.  Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.

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.
