BIOL 235 MIDTERM 2
1. between the origin and insertion which is usually located proximally in limbs
?
Answer Origin
2. 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
3. What is a mechanical advantage using the example of a lever?
Answer if the load is closer to the fulcrum and the ettort is farther from the fulcrum only a small about of
ettort is needed to move the load
