In anatomy, the term soft tissue refers to tissues that connect, support, or surround other structures and organs of the body, not being bone. Soft tissue includes tendons, ligaments, fascia, skin, fibrous tissues, fat, and synovial membranes, and muscles, nerves and blood vessels (which are not connective tissue). It is sometimes defined by what it is not. For example, soft tissue has been defined as “nonepithelial, extraskeletal mesenchyme exclusive of the reticuloendothelial system and glia”.
