Which layer of skin contains sweat glands?

The dermis is the layer of skin where sweat glands are located. It sits beneath the epidermis (the outer layer) and is composed of connective tissue, blood vessels, and various structures, including hair follicles, sebaceous (oil) glands, and sweat glands. Sweat glands are essential for regulating body temperature and maintaining homeostasis through the production of sweat, which helps cool the body when it evaporates from the skin's surface.

The stratum corneum is the outermost layer of the epidermis, mainly composed of dead skin cells and devoid of any glands. The hypodermis, or subcutaneous layer, lies beneath the dermis and primarily consists of fat and connective tissue, serving as insulation and cushioning for the body. The stratum basale is the deepest layer of the epidermis, where cell division occurs, but it also does not contain sweat glands. Therefore, the dermis is the only layer among the options given that specifically houses sweat glands.
