Cutaneous vasculature (Skin vasculature)

Sunday 15 May 2011 by Michel DĂ©marchez

In the skin, only the dermis and hypodermis are vascularized, the epidermis being a non-vascular tissue. The skin is richly supplied with a vascular network, largely exceeding its nutritive requirements, being also involved in thermoregulation, wound healing, immune reactions and the control of blood pressure. Cutaneous vessels belong to the arterial, venous or the lymphatic system; they are small branches from underlying vessels of the muscles that penetrate the subcutaneous fat, enter the deep reticular dermis and ascend vertically to the epidermis.
