Thick Skin - covers the palms of the hands and soles of the feet and is lightly pigmented.
Melanocytes - melanin-producing cells located in the stratum basale.
Paradoxically, melanocytes are unpigmented because they do not store melanin.
Melanin is transferred to other keratinocytes in membrane-bound organelles (melanosomes).
Stratum Basale - lightly pigmented with dark brown granules of melanin.
Sweat Gland - coiled tubular gland with simple or stratified cuboidal epithelium (lightly stained) and duct cells (dark staining).
Hair Follicle and Sebaceous Gland - common in thin skin. The sebaceceus glands are large cells with a central nuclei and foamy cytoplasm. These cells produce an oily, waxy substance called sebum that is released onto the surface of the skin.
