Which of the three lever systems involved in muscle mechanics would be the fastest lever—first-, second-, or third-class?
Discuss the functions of the different types of levers found in our body. How do these different types of levers make our body more useful. Explain each type of lever, the position of the fulcrum, load, and applied force and give an example of each.
What is an example of multiple lever types in the body during the same movement?
