===Subcutaneous tissue===
{{main|Subcutaneous tissue}}

The [[subcutaneous tissue]] (also hypodermis)  is not part of the skin, and lies below the [[dermis]]. Its purpose is to attach the skin to underlying [[bone]] and [[muscle]] as well as supplying it with [[blood vessel]]s and [[nerve]]s. It consists of loose [[connective tissue]] and [[elastin]]. The main [[cell (biology)|cell]] types are [[fibroblast]]s, [[macrophage]]s and [[adipocyte]]s (the subcutaneous tissue contains 50% of [[body fat]]). [[Fat]] serves as padding and insulation for the body.

[[Microorganisms]] like ''[[Staphylococcus epidermidis]]'' colonize the skin surface. The density of [[skin flora]] depends on region of the skin. The disinfected skin surface gets recolonized from [[bacteria]] residing in the deeper areas of the [[hair follicle]], [[gastrointestinal tract|gut]] and [[urogenital]] openings.
