Basement membrane
This electron micrograph of human skin shows the details of the basement membrane of an epithelium that is exposed to significant physical force. Numerous hemidesmosomes, which anchor the basal surface of the epithelial cells to the basal lamina, are present. Associated keratin filaments insert into the attachment plaques of the hemidesmosomes. Also visible are prominent anchoring fibrils that secure the epithelium to the underlying connective tissue. 45,000x
