Stratum granulosum

The stratum granulosum is three to five cell layers thick in thick skin and is composed of cells filled with prominent, basophilic, keratohyalin granules. These granules combine with tonofilaments (keratin intermediate filaments) to produce keratin. Simultaneously, the organelles in these cells degenerate, resulting in keratinized scales, which form the stratum corneum.  200x, 1000x
