Final answer:
The dermis is the skin layer that includes sweat glands, sebaceous glands, hair follicles, and nail roots. It is located beneath the epidermis and is essential for various skin functions and protection.
Step-by-step explanation:
The layer of skin that contains the sweat glands, sebaceous glands, hair follicles, and nail roots is called the dermis. The dermis is situated beneath the thin outer layer known as the epidermis and is comprised of tough connective tissue. Within the dermis, one finds blood vessels and various embedded structures including sweat glands (which produce sweat for thermoregulation), sebaceous glands (associated with hair follicles and produce sebum), hair follicles (from which hair originates), and the roots of nails. These structures are all important components of the integumentary system, responsible for numerous functions such as temperature regulation, protection, and sensation.
The layer of skin that contains the sweat glands, sebaceous glands, hair follicles, and nail roots is called the dermis. The dermis is a thicker layer beneath the epidermis and is composed of tough connective tissue. It holds many embedded structures such as blood vessels, nerves, muscles, and glands.
