The Tongue, Mandible, Hyoid System.

The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affect this functional arrangement. Notwithstanding this system considered as a functional arrangement, may offer various clinical explanations, it does not hold anatomical connections with the posterior region of the cranium, thus it should not be refered to as a craniocervical arrangement. For this reason a new interpretation of such system as the tongue, mandible, hyoid system should be considered. Such functional reinterpretation between these three anatomical structures allows further comprehension of specific clinical conditions connected to deglutition aspects or the temporomandibular joint, for such needs to be taken into account during clinical diagnosis and treatment.
