The periodontal membrane is not a joint in the skeletal sense, but rather a specialized fibrous tissue that anchors the tooth within its socket.12

It facilitates the brain's control of chewing muscles by housing sensory nerve endings that provide proprioceptive feedback. These nerves detect stimuli from within the body, sending critical information to the central nervous system regarding the position and pressure of the teeth. This sensory input allows the brain to coordinate the activity of the muscles of mastication—such as the masseter and temporalis—ensuring precise and effective movement during chewing and swallowing.13
