Question

The ________ is the first class lever is the most common lever in the human body.

Answer 1

The first class lever is the most common lever in the human body. True/False

Answer:

False

Explanation:

In first-class levers, the position of the fulcrum is between the effort and the load.  In these levers such as scissors, if the effort (child) is farther from the fulcrum than the load, a  heavy load can be moved. There are few first-class levers in  the human body.  

One of the examples of such a lever is the head resting on the vertebral column. When the head is raised, the contraction of the posterior neck muscles provides the effort and the fulcrum is formed by the joint between the atlas and the occipital bone. Third class levers are the most common types present in the human body.
