[8] Simultaneous to Wood's work in Edinburgh, Charles Pravaz of Lyon also experimented with sub-dermal injections in sheep using a syringe of his own design. Hypodermis. [27], Device to inject substances into the circulatory system, For the theory on mass media effects, see, "Hypodermic" redirects here. [17], Hypodermic needles are normally made from a stainless-steel tube[18] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The hypodermis, sometimes also known as the subcutaneous tissues, is the most interior layer of human skin. These injections (shots) are given into fatty areas of the body called injection sites.
