Assignment 16779

Every day we open and close a door but how often do you think about the motions that actually take place? 

Using approximately 400-500 words, describe which motions and muscles in the right elbow, forearm, wrist, and hand are responsible for turning a doorknob clockwise and pushing open a door. What if the motion was reversed and you had to turn the knob counter-clockwise and pull open the door? Include at least two scholarly references (using APA formatting and style) to guide your answers.
