What is control and coordination?

All these movements discussed in the previous section are in response to the environment.

That means, every change in the environment elicits a movement in response .

Example; if you fall down and get hurt, you immediately reach out for first aid.

We analyze and recognize various events or stimuli and display only the correct response.

(Stimulus (singular) / Stimuli (plural) - Things that cause an action or response)

 

Thus there is control and coordination in our movements with respect to events around us.
