The granular layer of the epidermis is found beneath its horny layer. It consists of 3 to 5 layers of cells that have already flattened considerably, whose nuclei are in the process of degenerating. Its granular appearance is due to the presence of keratohyalin granules and  keratinosomes. The latter are part of the body’s “intercellular cement” that spreads into spaces between cells. Keratohyalin helps make keratin more resistant and decompose in the amino acid “bath” that is part of N.M.F..
