Abstract: The authors suppose that the parenchymal cells of the 1st type of the Chievitz' juxtaoral organ may be paraneurons with respect to their secretory function which may modulate the afferent dentritic zones of different kinds of sensory nerve formations - SNF (endings). In this respect the parenchymal cells of the 1st type may have the same functions as glomus cells in the glomus caroticum or Merkel cells in the epidermis. As to the function of the juxtaoral organ the authors presume its multimodal mechaosensory function, as it contains 4 to 5 kinds of SNF (intraepithelial nerve fibers, simple arborizations, maybe Ruffini SNF, glomerular SNF, and simple sensory corpuscules) with 2 basic different modes of adaptation: simple SNF and Ruffini SNF adapt slowly, some intraepithelial nerve fibers, glomerular SNF and lamellar corpuscules adapt rapidly. The exstence of this organ already in newborn indicates its important mechanosensory function connected with nutrition, reflexes and oral cavity walls tonus regulation, later on, connected with mastication and speech, too. As to the classification, the juxtaoral organ belongs to complex SNF with a constant accumulation of different kinds of SNF.
