The “Lasagna Slice” is one of my favorites for understanding the anatomy and physiology of the connective tissue layers. Hair, sweat, and oil glands are in the epidermis and dermis – our skin. The hypodermis is defined as the area from below the skin to above the deep fascia, and includes the superficial fascia layer as well as nerve / blood / lymphatic vessels and fat. Cupping impacts all of these, as well as multiple body functions because of the autonomic nerves coursing through this corridor. Source unknown.
