(144).jpg "Motor Control Theories And Characteristics! Trivia Quiz")
The human body can move in different ways, and there have been various theories put across to explain how we attain coordinated movement. How well do you actually understand these theories and their application in real life? This trivia quiz will test you on motor control theories and characteristics based on some real-life scenarios that people have undertaken regularly. Do give it a shot and see if it helps you understand motor control better.

Important source of feedback
