[Sensory support of tongue movements in the sound-forming process in infants in the lst year of life].
The structural and functional formation of tongue tactile sensory formations were correlated in infants. Heterochronicity was recorded both in build up of receptor formations in different areas of the tongue (tip, body, root) and sensory control of its movements related to sound formation. Receptor formations of the root of the tongue are formed first of all, hence the first sounds that are uttered by infants are primarily velar ones, followed by the appearance of the medio-lingual and later by dorsal sounds.
