The subcutaneous tissue or subcutis is the layer of loose connective tissue directly underlying the dermis.^[1] It is mainly composed of adipose tissue. Its thickness depends on the amount of fat present.^[2] 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. <gallery> Image:Implantsyringe.JPG|10.8mg implant syringe for subcutaneous use Image:Implant.png|A typical injection site post-implant.
