Gourt Home::Gourt :: Subcutis
The 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. Directly below the subcutis is usually a layer of muscle (covered in a fascia) or bone (covered in periosteum).
Subcutaneous (abbr: subq) injections are given by injecting a fluid into the subcutis. It is relatively painless and an effective way to administer particular types of medication. Certain depot injections, such as goserelin, are a solid or oil-based medication which is administered subcutaneously where it releases its agent slowly over a period of weeks.
Subcutaneous layer of skin
The dermis rests on this layer, sometimes referred to as the hypodermis. It consists of loose connective tissue and large amounts of adipose tissue (fat). This is the body's insulation and energy reserve for energy. Continuous bundles of elastic fibers connect the subcutaneous tissue with the dermis. The blood vessels that supply the skin and help regulate body temperature run through the subcutaneous layer. This layer also contains nerves and nerve endings.
