Question #44292
Explain the way nervous system helps to coordinate complex and intricate movements of hand to play a piano ,or write alphabets?
Expert's answer
The intention to contract a skeletal muscle begins in the motor association (premotor) area of the frontal lobes. This is where we plan our behavior—where neurons compile a program for the degree and sequence of muscle contractions required for an action such as dancing, typing, or speaking. The program is then transmitted to neurons of the primary motor area (precentral gyrus), and then the primary motor area sends signals to the cerebellum, which integrates them. It also ensures that all of the muscles work together to produce smooth, coordinated voluntary movements. The cerebellum assists the learning of new motor skills
like playing the piano or hitting a baseball.
