Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth.[1] Soft tissue connects, surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes.[1][2]
It is sometimes defined by what it is not – such as "nonepithelial, extraskeletal mesenchyme exclusive of the reticuloendothelial system and glia".[3]
