Question

cervical flexion is an example of a first class lever.
true
false

Explanation:

In biomechanics (a subfield of Natural Science, specifically related to human movement and anatomy), a first - class lever has the fulcrum between the effort and the load. During cervical flexion, the atlanto - occipital joint acts as the fulcrum, the muscles at the back of the neck (effort) work to move the head (load), with the fulcrum in between. So cervical flexion is an example of a first - class lever.

Answer:

True
