The '''subcutaneous tissue''' or '''subcutis''' is the layer of tissue directly underlying the [[Cutis (anatomy)|cutis]]. It is mainly composed of [[adipose tissue]]. Its thickness depends on the amount of fat present.<ref>[http://www.skincarephysicians.com/skincancernet/glossary.html SkinCancerNet Glossary]</ref> Its physiological function includes insulation and storage of nutrients.
==Injections==
'''Subcutaneous''' [[injection]]s 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.
