Survey of the development of laryngeal epithelium.

An overview of the developing laryngeal epithelium has been presented to establish the norm. The sequential relationships of the formation of the protective laryngeal covering, cellular and glandular, have been reviewed. The topographical distribution of the epithelial elements in the human larynx are illustrated in the adult and contrasted in the child. Unique and previously undescribed cellular ultrastructure and transition areas have been identified. Biological integrationof form and function is again well illustrated in the epithelium of the human larynx.
