Where and what is the dermis?

Where is the epidermis and dermis located?

The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

Where is the papillary layer located?

The papillary layer is the superficial layer of the dermis that projects into the stratum basale of the epidermis to form finger-like dermal papilla (plural = dermal papillae) (see Figure 5.6).

What are the 3 layers of the dermis?

What tissues are in the dermis?

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.

Is the dermis a tissue or an organ?

Organ Level — Dermis

This dermal part of the skin (organ) is vasculated (has blood vessels) and is innervated (has nerves). As described earlier, the dermis is sparsely populated with fibroblasts that produce collagen and elastin fibers in the extracellular matrix. This leads to a strong and elastic tissue structure.

Do humans have 7 layers of skin?

There are seven layers of skin and each layer serves different functions. The skin is the largest organ in the body and it covers the body’s entire external surface.
