uranisc-, uranisco- +
(Greek: roof of the mouth; literally, "little vault of heaven")
2. An operation for repairing a cleft palate (roof of the mouth).
The fixed portion, or palate proper, supported by the maxillary and palatine bones, is called the hard palate to distinguish it from the membranous and muscular curtain which separates the cavity of the mouth from the pharynx (cavity at the back of the mouth) and is called the soft palate, or velum (membranous, or pliable texture, covering).
