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.

What type of lever is the vastus medialis? Support your answer with a free body diagram. The vasti muscles are used both for sit-to-stand AND stand-to-sit movements. Which of these two tasks represents a concentric contraction and which represents an eccentric contraction? Which muscle (vastus lateralis or medialis) do you think is more important for doing a slow, controlled stand-to-sit transition? If you witnessed your grandfather "plopping" (doing an uncontrolled sit) into a chair, would you recommend giving him eccentric or concentric strengthening exercises for his vasti muscles? Justify your answer.
Determine the muscles involved in common movements Lists the joints used Discuss the physiology of the movement Movements: Jumping (search spring actuated models) Frog Muscles involved: quadriceps, hamstrings, and glutes Joints: hip joint, knee joint, and ankle joint Physiology of the movement: The moment when the frog jumps, such as a catapult or archer’s bow, the tendons which wrap around the ankle release energy, which causes a rapid extension of the ankle that drives the frog forward.
