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 geosphere can be regarded as the collective name that is used to call the atmosphere of the earth lithosphere as well as hydrosphere, and cryosphere.
- The geosphere can be regarded as sphere which contains the rocks as well as minerals on Earth
- The geosphere is also the sphere with abiotic/non-living parts of soils as well as the skeletons of animals, it also contains sediment as well as rocks.
- An atmosphere can be regarded as the layers which consists of gases which envelope a planet.
Therefore, geosphere is collection of spheres containing sediments as well rocks.
