3 Principle Layers of Epidermis |
1. Stratum basale— keratinocytes capable of dividing — melanocytes — touch and pressure detecting cells 2. Stratum spinosum — keratinocytes that are non-dividing and beginning to fill with the protein keratin — some dendritic cells that function in immunity — some melanocytes 3. Stratum corneum— composed of corneocytes — completely dead and filled with the protein keratin — cells slough off in a process called de-squamation |
