Dermis

Dermis
Latin dermis; corium
Code TH H3.12.00.1.03001

The dermis is a layer of skin between the epidermis (with which it makes up the cutis) 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]

Components of the Dermis

The dermis is composed of three major types of cells[3]: 1. Fibroblasts 2. Macrophages 3. 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].

Stratum papillare

The stratum papillare sends conical elevations (papillae) into the epidermis which contain either terminal networks of blood capillaries or tactile Meissner's corpuscles. [4]

Stratum reticulare

The stratum reticulare possesses coarser and more regularly arranged collagenous fiber bundles.
