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.
The ancient Egyptians used the stars to tell when a flood was going to happen. Every summer a flood would happen but this also happened when the bright star Sirius rose before the sun.
