dermis

[New Latin, back-formation from Late Latin epidermis, epidermis. See epidermis.]

The layer of skin just below the epidermis consisting of vascular connective tissue.

Normal skin anatomy. (Jarvis, 2000)

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.

• hoof d. — a greatly modified dermis, continuous at the coronet with the common dermis of the skin; the modified dermis supports the horn of the hoof.

A graphic representation of the interface between skin epithelium and the underlying connective tissue. Zone B, indicating the region of overlapping projections of epithelium and connective tissue, is the papillary dermis. Zone C, indicating the region of dermis that lies immediately subjacent to the interdigitations of epithelium, is the reticular dermis.

The dermis is a layer of skin between the epidermis and subcutaneous tissues, and is composed of two layers, the papillary and reticular dermis.^[1] Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix (previously called ground substance).^[2]
