According to the gate control theory of pain, the structure that is the likely location of the gate is: Group of answer choices
Romashka-Z-Leto [24]

According to the gate control theory of pain, the structure that is the likely location of the gate is the substantia gelatinous.

<h3>What is substantia gelatinous?</h3>
  • A group of cells called the substance gelatinosa can be found in the spinal cord's gray matter (dorsal horns).
  • It receives direct input from the dorsal (sensory) nerve roots, particularly those fibers from pain and thermoreceptors, and is present at all levels of the cord.
  • The spinal cord has a system that permits pain signals to be amplified in the brain before being processed at the spinal cord itself, or attenuated there, in accordance with the Gate Control Theory of Pain.
  • The "gate" is the device that either permits or forbids the transmission of pain signals.
  • To feel intense pain if the gates are more open since many more pain signals will flow through to the brain.
  • The likelihood that you will feel less discomfort increases as the gates are more tightly shut.

Graph y = -2x +3 and its inverse.
Gnesinka [82]
The graph of y = -2x + 3 is a straight line

Its slope is - 2

Its y-intercept is + 3

To draw the line you can use these two points (0,3) and (3/2 , 0)

This line does ont pass through the third quadrant. It comes downward from the second quadrant, touches the y-axis at y =3, continues on the rirst quadrant, touches the x-axis at x = 3/2, and contiues into the fourth quadrant.


Graph of its inverse

Exchange y and x in the given function and solve for the new y

x = - 2y + 3 => y = - x/2 + 3/2

It is also a straight line;
Its slope is -1/2
Its y-intercept is 3/2

It is also in the second, first and fourth quadrant

Use these two points to draw the line (0,3/2) and (3,0).

You do not need to know to draw this, but the inverse of a function is its reflection through the line y =x.
