What are the major components of the dermis?

The components of the dermis comprise the fibrous tissue and the dermal matrix formed by cells in the interstitial components (Fig. 1.22). The major components mainly consist of collagen fibers (mainly types I and III), with smaller amounts of elastic fibers, reticular fibers and matrix.

Why dermis is called True Skin?

What is the dermis?

The inner layer of the two main layers of the skin. The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.

What are the two primary features of the dermis?

What are the two primary features of the dermis? (It contains fibers that give skin its strength and elasticity, and it contains sensory nerve cells that give skin its sense of touch.)

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.

How many layers are in the dermis?

It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis.
