Proprioceptive sensitivity and orofacial functions

: Proprioceptive sensibility from stimulation of muscle, ligament articular and vestibular receptors plays a determining role in the regulation of tone, of the resting position of the mandible, of head posture and of the closure pathway of the mandible. Studies conducted on temporomandibular joints of fetuses and adult subjects failed to demonstrate the specialized corpuscles (a fact previously noted by Ramfjord) in the temporomaxillary joint capsule, described typically in other joints. In contrast, however, histology showed a particularly rich population of muscle receptors adjacent to this joint, this being only one of several particular characteristics.
