what's the principal cell type associated with the dermis (not epidermis) in the skin? cheers!?

Answer 1

The dermis or corium is made up of connective tissue, cellular elements and ground substance. It has a rich blood and nerve supply. The sebaceous glands and the shorter hair follicles originate in the dermis. The corium can be divided into the papillary (upper) and reticular (lower) layers.
The connective tissue consists of collagen fiers, elastic fibers and reticular fibers--all contribute to the support and elasticity of the skin.
The collagenous fibers are made up of eosinophilic acelular proteins responsible for nearly a fourth of man's over-all protein mass.
Elastic fibers are thinner than most collagen fibers and are entwined among them. They are composed of protein called elastin.
The reticular fibers are thought to be immpature collagen fibers.
The cellular components are mesodermal cells (a reticulohistiocytic group fibroblasts, histiocytes, and mast cells...all are called reticulum cells), a myeloid group, and a lymphoid group.
Sometimes plasma cells are seen, but rarely, unless there is an inflammatory condition.
