Subcutaneous tissue

The subcutaneous tissue or subcutis is the layer of loose connective tissue directly underlying the dermis. It is mainly composed of adipose tissue. Its thickness depends on the amount of fat present. Its physiological function includes insulation and storage of nutrients.

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.
