The dermis consists of a papillary and a reticular layer which serve to protect and cushion the body from stress and strain. Differentiate among the regions of the dermis and the hypodermis. The dermis is divided into a papillary region and a reticular region.
A graphic representation of the interface between skin epithelium and the underlying connective tissue the reticular dermis. 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.n addition, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels are present in the dermis. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells.
