The Chievitz juxtaparotid organ

The Chievitz juxtaparotid organ represents a macroscopic longitudinal formation, which is developed from oral cavity ectoderm in its lateral wall. As to its function, the organ probably represents a mechanosensor with different qualities of perception. The information coming from its sensors takes part in different activities of the lateral wall of oral cavity during sucking, swallowing, mastication, speech, protecting reflexes and wall tonus. The Chievitz juxtaparotid organ is not only a morphologically interesting structure, but is of great importance also for clinic and surgical pathology of the oral cavity.
