Cutises, also known as the plural form of cutis, refer to the skin covering the human body. However, antonyms for this word include unfamiliar terms such as mucosa, epidermis, and dermis. The mucosa is the mucous membrane lining the interior of the body cavities, while the epidermis refers to the outermost layer of the skin. The dermis, on the other hand, is the layer of the skin that contains the hair follicles and sweat glands. While these terms may seem unfamiliar, they are essential for medical terminology and understanding human anatomy. As professionals in the health industry, it's vital to have a comprehensive understanding of such terminology.
