The principal role is to provide strength to the Epidermis and allow the skin to flourish. It contains blood vessels and nerve ends. The dermis consists of two layers: The papillary layer is a thin outer layer of areolar connective tissue with fingerlike projections called dermal papillae that protrude into the epidermis.In the hands and feet, the dermal papillae generate epidermal ridges (sweat from the epidermal ridges leaves fingerprints). The function of the dermis is to bind the entire body together like a body stocking. The cells in all of the layers except the stratum basale are called keratinocytes.
