RESUMO
I. Under scanning electron microscope, the vascular network of the cutaneous, subcutaneous, and deep fascia in planta can be divided into five layers according totheir vascular morphological characteristics. They are as following: the papillary layer, the subpapillary layer, the deep dermal layer, the subcutaneous layer, and the deep fascia layer. 2. The papillary layer is the most superficial one, it is easy to recognize that there are five types of capillary network: the single loop, the multiple loop, the tower-like type, the finger-like type, and irregular type. 3. The network in the subpapillary layer is polygon-like, parallel to the surface of skin. 4. In the deep dermal layer, there are many vascular balls in the vascular trunks. 5. The subcutaneous layer: The vascular networks are limited by fat lobules. 6. The vascular-trunks run across each other and anastomose each other in deep fascia layer.
