Question:

Langerhans cells and melanocytes both have protective functions, though melanocytes protect the skin against UVA and UVB radiation. Langerhans cells are found in the epidermis and assist lymphocytes in processing foreign antigens. Eccrine glands secrete sweat, which aids in temperature regulation and excretion of water and electrolytes. Reticular fibers make up part of the structure of the extracellular material.
