I have seen my teachers giving different expressions, when they explain something to us, or when we explain our question to them, sometimes I saw different expressions when they are listening to our wrong answers asked by them itself ??? w.hy these expressions occur on the faces of persons, I am noticing from a quite a time on the face of my school teachers. But Is it due to how the brain controls our expressions? Or what? Please Tell, I am curious to know about it.?
Dear student,
The facial expressions of human being are voluntarily or involuntarily occur under the control of the different neural tract such as pyramidal for voluntary expressions and extra pyramidal tract for involuntary tracts.
