Epidermal Layers Mnemonic in ESPAÑOL

"La BASE tiene ESPINAS GRANULOSAS que con la LUZ, tu CORNEA las ve bien"

Basal => columnar like cells

Spinosum => cuboidal like cells & demosomes in between (AutoAb: Pemphigus Vulgaris)

Granulosum=> polygonal cell w/ basophylic granules

Lucidum => thick layer ONLY in palms & soles

Corneum => flat, anucleated, cornified cells
