The thickness of human skin varies depending on several factors including location on the body. Generally, skin on areas such as the palms of the hands and soles of the feet can be thicker (up to about 4mm), while the skin on the eyelids is thinner (around 0.5mm). Overall, the average thickness of skin is typically around 1 to 2 mm, which aligns with option (C). When considering the structure of skin, remember it consists of multiple layers, primarily the epidermis and dermis. The epidermis is the outermost layer, providing a protective barrier, while the dermis supports its structure and contains essential elements like blood vessels, nerves, and sweat glands. Together, they work to maintain homeostasis and protection against environmental threats.
