Our volitional centre, the motor cortex, is where we impose specific facial expressions in order to convey the desired message or because the situation requires it.
<h3>What is the purpose of the motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves.
- It is anterior to the central sulcus and a portion of the frontal lobe.
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
<h3>What kinds of motions does the motor cortex regulate?</h3>
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motor neurons to regulate motor behaviour.
- For the execution of movements to be precise, coordinated muscle activation patterns are required.

<span>The calculated to surface area for red blood cells by Gorter and Grendel found to be 36u2.
The surface area that would be covered once they spread across the surface of the water is 72u2.
If they spread across the surface area will double. This is because the lipid bilayer with phospholipid the head faces the water on each surface of the membrane.
It clearly shows that there must be more to membranes than lipid bilayer because membranes grew and the surface tension of membranes is much lower than those of pure lipid structures.</span>
