Dermis

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. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix (previously called ground substance).

Components of the Dermis
The dermis is composed of three major types of cells : 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.

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.

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