The different types of levers in the human body. These levers consisting of First Class Lever, Second Class Lever, and a Third Class Lever. The list below describes such skeletal movements as normally are possible in particular joints of the human body.
The handles can be bent, for example, so that the load applied by the hand is aligned with the arm, rather than at an angle, thus reducing muscle fatigue. It is especially important for factory workers who use pliers continuously and helps prevent carpal tunnel syndrome .
