Dermis

From Wikipedia, the free encyclopedia

Jump to: navigation, search
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]
