title: Branching microvilli in the nasal respiratory epithelium.
abstract: In an ultrastructural study of the respiratory epithelial covering of 14 human nasal mucous polyps, some of the microvilli overlying the ciliated cells were shown to exhibit a complex form of branching with a resultant increase in surface area. This apparently original observation is of uncertain significance but is not of definite pathological significance.
