Tegument

A tegument is a natural outer covering, such as the skin, shell, or husk, that provides protection or insulation to an organism or object. This protective layer can be diverse in composition, ranging from the tough exoskeletons of insects to the delicate epidermis of humans. It serves vital functions like safeguarding against environmental factors like ultraviolet radiation, pathogens, and physical damage, as well as regulating internal conditions by controlling water loss and temperature. In biology, the term emphasizes the external surface and its roles in defense and interaction with the external environment.
