major cells of epidermis; tighlty connected by desmosomes; millions slough off everday; produce fibrous kertain
the less numerous type of sweat gland; produces a secretion containing water, salts, protein and fatty acids
an abnormal mass of proliferating cells; benign remain localized and malignant are cancers which can spread to other organs
tissue damage inflicted by intense heat, electricity, radiation or certain chemicals all of which denature cell proteins and kill cells in the affected areas
small, nipple-like projection; eg dermal papillae are projections of dermal tissue into the epidermis
protective cells the engulf antigens, migrate to lymph nodes and present the antigen to T cells, causing them to activate and mount an immune response; those in the skin are sometimes called langerhans cells
receptors located throughout the skin that respond to stimuli arising around the body; part of the nervous system
