Abstract

Histological analysis of the human vocal folds, focused particularly on the lamina propria of the vocal muscle of fetuses, infants, and adults in horizontal laryngeal sections, allowed us to show the differences in morphology and composition according to the laryngeal development. Our results indicate that the origin of the vocal fold is independent of the origin of the other portions of the larynx, and the influence of the zone known as macula flava in the maturation of the vocal fold is an age-related process.
