Human skin consists of two layers, the Epidermis and the Dermis. The Hypodermis (AKA Subcutaneous Tissue) is also worthy of mention when studying the skin.
Epidermis
Stratum Corneum, (The protective, horny Layer).
Stratum Lucidum (May not actually exist. Included here for completeness).
Stratum Granulosum (Granular Layer, containing melanocytes and basophilic granules).
Stratum Spinosum (Prickly Layer).
Stratum Germinativum (Base Layer, keratinocytes form here. Also melanocytes).
Dermis
Papillary Layer (Loose connective tissue).
Reticular Layer (Dense connective tissue, houses glands and hair follicles).
