Sažetak
Differentiation of epiglottal epithelia during human development was for the first time investigated by the light microscopy and documented in celoidine collection of human embryos from the Archive of the Department of Histology and Embryology, School of Medicine University of Zagreb, Croatia. At 6 weeks epiglottal swelling was found to be covered by a simple squamous epithelium consisting of a single layer of cell. At 8 weeks epithelium changed to a two-layered cuboidal epithelium which at the end of the 8th week transformed to multilayered columnar epithelium without cilia and goblet cells. In the one-day-old newborn, the majority of epiglottis was found to be covered by the mature ciliated columnar pseudostratified epithelium. This enexpected finding is in contrast to the domination of the stratified squamous epithelium found at the age of 13 years and in 35-years-old adult. Reversal of proportion covered by different types of epithelia between birth and puberty / adulthood is probably connected to the establishment of the air-flow which could be stimulating for differentiation of stratified squamous epithelium.
