[New Latin, back-formation from Late Latin epidermis, epidermis. See epidermis.]
Deep layer of the skin, beneath the epidermis, containing blood vessels, muscles, nerve endings, and dense irregular connective tissue.

The corium; the principal layer of skin between the epidermis and the subcutaneous tissue; made up mostly of a network of collagen fibers but also containing nerves, blood vessels, cells and other fibers. It is divided into papillary and reticular parts, and when tanned forms leather.
The layer of skin just below the epidermis consisting of vascular connective tissue.

The dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain. 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.[1] The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix (previously called ground substance).[2] It also contains Mechanoreceptors that provide the sense of touch and heat, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells.

The dermis is composed of three major types of cells[3]: Fibroblasts, Macrophages, and Adipocytes.
Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and glycosaminoglycans[3].
The papillary region is composed of loose areolar connective tissue. This is named for its fingerlike projections called papillae, that extend toward the epidermis and contain either terminal networks of blood capillaries or tactile Meissner's corpuscles. [4]
The reticular region lies under the papillary region and is usually much thicker. It is composed of dense irregular connective tissue, and receives its name from the dense concentration of collagenous, elastic, and reticular fibers that weave throughout it. These protein fibers give the dermis its properties of strength, extensibility, and elasticity. Also located within the reticular region are the roots of the hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
