It shows three divisions of the skin, viz., the epidermis or epithelial part; the corium or true skin or fibrous part; and the subcutaneous tissue, panniculus adiposus or fat layer. In the upper part of the corium, called the papillary layer, are the skin papillæ containing vessels and nerve terminations and lymph spaces, while the middle and deep layers contain the vascular plexuses, the hair follicle, its muscle, and sebaceous glands, and the tortuous sweat duct which traverses it to reach the sweat coil situated in the fat layer. |
