    • ‘The cells of stratum basale constitute a single layer of columnar or cuboidal cells in contact with the basement membrane and connective tissue of the dermis.’
    • ‘As a basement membrane separates an epithelium from the underlying lamina propria or supportive tissue, so it also separates the follicle from the theca.’
