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.
The sponge-like structure, as well as the high salt content of water and the <span>ease of contaminating water contribute to the environmental stress on a coral reef.
Invasive species. Native grasses have evolved with the normally-occurring grazing organisms to achieve a level of reproduction which sustains the grasses despite the grazing. An invasive species disrupts this ecological balance that took millions of years to develop by eating the grass at a rate that exceeds the rate for the grass to re-seed itself and maintain its own population. The invasive species easily decimates the grass population.
A typical leaf has three main layers. ... Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water los
