Is your arm a lever?
A bent arm is a Class 3 lever. The pivot is at the elbow and the forearm acts as the lever arm. The biceps muscle provides the effort (force) and bends the forearm against the weight of the forearm and any weight that the hand might be holding. The load is further away from the pivot than the effort.

What kind of lever is a jaw?
When biting using your front teeth, your jaw works as a third-class lever. The input force (applied by your jaw muscles) occurs between the fulcrum (the joint where your jaw bone connects to your skull) and the output force which is applied to the apple. Your forearms work as third-class levers.
Is wheelbarrow a lever?
