Which layer of the skin contains sweat and sebaceous glands?

• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Subcutaneous layer

Answer: (B)

The dermis is the correct answer because it is the layer of skin located beneath the epidermis and is rich in various structures, including sweat glands and sebaceous (oil) glands. The dermis is responsible for the skin's strength and elasticity, as it contains collagen and elastin fibers. In addition to sweat and sebaceous glands, the dermis also houses blood vessels, nerve endings, and hair follicles, which are essential for various physiological functions and sensory perception. The epidermis, on the other hand, is the outermost layer of skin, primarily composed of keratinocytes and is mainly responsible for protection against environmental damage, but it does not contain any glands. The hypodermis, also known as the subcutaneous layer, lies beneath the dermis and is made up of fat and connective tissues, serving mainly as insulation and energy storage, but it does not contain the sweat or sebaceous glands found in the dermis. Therefore, the dermis is the specific layer that houses these glands necessary for regulating body temperature and maintaining skin moisture.
