Mand

ible The mandible, also known as the lower jaw, is a crucial component of the facial skeleton in humans. It is one of the four bones that form the lower face and is responsible for the movement of the lower jaw, providing essential support and protection for the teeth and tongue. The mandible helps to define the shape of the face and plays an important role in speech, eating, and facial expressions. Properly functioning mandibles help with jaw alignment and the prevention of dental problems such as overcrowding and jaw joint dysfunction.
