What controls this ability to connect through the body movements and facial expressions of others?
lianna [129]

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.

True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.
