[In favor of glossology. Knowledge and practice regarding the tongue].
Despite recent advances in embryology, lingual morphologic development remains partially obscure. Neurophysiology of development of tongue in the fetus and young infant is dominated by the motor orality which requires, at an early stage, both sensorial and motor organization of the brain stem. Starting with this baseline sensorial organization, there develops in the young child a increasingly complex growth gradient of lingual gnosis and praxis (general oral), starting with the spoon-feeding praxis at about 6 months of age. The language eclosion then follows during the second year with helicoidalization of mandibular gesture leading to the "form-inform" tongue at about 7 years of age possessing proprioception of a non-fusorial sensory origin--the absence of this would cause it to be at the mercy of the teeth. An organ which lengthens by contracting clearly merits its own science....
