Question

dorsiflexion is an example of what type of lever?

a) 1st class

b) 2nd class

c) 3rd class

d) 4th class

Explanation:

In the human body, during dorsiflexion (movement of the foot upward), the tibialis anterior muscle (effort) acts between the fulcrum (ankle joint) and the load (weight of the foot and any additional load). This configuration matches a 2nd - class lever, where the load is between the fulcrum and the effort.

Answer:

b) 2nd class
