Does the Human Lower Jaw Rely Solely on Muscles or Cartilage to Stay Attached to Your Skull?
The human lower jaw, or mandible, is a unique bone that connects to the skull at two points called the temporomandibular joints (TMJs). These joints allow the jaw to move smoothly in a variety of directions, including up and down, side to side, and forward and back.
Contrary to popular belief, the lower jaw is not held in place solely by muscles. While muscles do play a role in jaw movement, they are not responsible for keeping the jaw attached to the skull. Instead, the TMJs are lined with a layer of cartilage that acts as a cushion and helps to prevent the bones from rubbing against each other. The cartilage also helps to absorb shock and distribute forces evenly across the joint.
