The subcutaneous tissue or subcutis is the layer of tissue directly underlying the cutis. It is mainly composed of adipose tissue. Its physiological function includes insulation and storage of nutrients.
[edit] Injections
Subcutaneous injections are given by injecting a fluid or a solid pellet into the subcutis. It is used to administer a variety of medical treatments. Subcutaneous injections of fluid are used to administer vaccines and medications. A pellet may be injected to deliver long-lasting doses of medication such as goserelin. Subcutaneous injections provide slow and constant absorption and are one of the parenteral routes of administration.
