Histological Studies of Human Vestibular Membranes

Abstract

Human vestibular membranes of the cochlea were studied by light microscopy using the surface preparation technique. The mesothelial cells were large, flat and elongated and they were arranged in a radial fashion slightly bent toward the apex of the cochlea. The form and the arrangement of the epithelial cells became more irregular with aging.
Epithelial clusters or epithelial bands were often observed in the membranes of adults.
Blood vessels were occasionally found on the mesothelium of the vestibular membrane near the apex of the cochlea.
