◉ What happens during REVERSE MUSCLE ACTION?
Answer: specific movements of the body the actions are reversed
THEREFOR the positions of the origin and insertion of a muscle are
switched
◉ What is a mechanical advantage using the example of a lever?
Answer: if the load is closer to the fulcrum and the effort is farther
from the fulcrum only a small about of effort is needed to move the
load
