Questions
Name the 4 four muscles of the rotator cuff. What are the individual actions of each of
these muscles? What is the combined purpose of these muscles at the shoulder joint?
Follow a red blood cell from the left ventricle until it reaches the superficial musculature
of the left thumb. List all the blood vessels that this blood cell must travel through to
complete its journey. Where do the name changes in these arteries occur?
