The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands. The role of the dermis is to support and protect the skin and deeper layers, assist in thermoregulation, and aid in sensation .

What happens in the dermis?
Dermis. ... The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels . The nerve endings sense pain, touch, pressure, and temperature. Some areas of the skin contain more nerve endings than others.
How does the dermis protect the body?
Protecting the rest of the body: The dermis contains phagocytes , which are cells that consume potentially harmful toxins and impurities, including bacteria. The dermis already protects the body, but the phagocytes provide an additional layer of protection from anything harmful that has penetrated the epidermis.
What is difference between dermis and epidermis?
Dermis and epidermis are basically protective outer layers of the body. The main difference between dermis and epidermis is that dermis is a tissue below the epidermis, containing living cells whereas epidermis is the outermost part of the body , protecting it from dehydration, trauma, and infections.
How thick is the epidermis and dermis?
The dermis is a tough but elastic support structure that houses nerves, blood vessels, lymphatics, and cutaneous appendages (pilosebaceous units, eccrine and apocrine sweat glands). It is thicker (averages 1 to 4 mm) than the epidermis which is about as thin as piece of paper.
How do the epidermis and dermis protect the body?

Keratin, a protein made by cells found in the epidermis, gives skin its toughness and strength, and protects skin from drying out .

What is the function of melanin?
In its various forms, melanin fulfills a variety of biological functions, including skin and hair pigmentation and photoprotection of the skin and eye . Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis.
Which disorder is a cause of systemic altered inflammatory response?

What types of protection does the skin offer the body?
The skin acts as an external barrier to bacteria, preventing infection and protecting the internal organs. The skin also protects the body from ultraviolet radiation using the pigment barrier formed from melanocyte cells found in the top of the papillary dermis and a protein layer found in the epidermis.
