What cell types are found in the dermis?
The dermis is composed of three major types of cells - fibroblasts, macrophages, and adipocytes.
Apart from these cells, the dermis is also composed of matrix components such as collagen, elastin,and extra fibriliar matrix (gel like substances).
The papillary dermis is the uppermost layer of the dermis and is composed of loose areolar conective tissue.
The reticular dermis is the lower layer of the dermis and is composed of dense irregular connective tissue featuring densely packed collagen fibres. Within the reticular region are the roots of hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
Dermal papillae are small extensions of the dermis into the epidermis. At the surface of the skin, they appear as epidermal or papillary ridges, commonly called as the finger prints.
