Soft tissue Soft tissue In anatomy, soft tissue includes the tissues that connect, support, or surround other structures and organs of the body, not being hard tissue such as bone. Soft tissue includes tendons, ligaments, fascia, skin, fibrous tissues, fat, and synovial membranes (which are connective tissue), and muscles, nerves and blood vessels (which are not connective tissue). It is sometimes defined by what it is not. Soft tissue has been defined as "nonepithelial, extraskeletal mesenchyme exclusive of the reticuloendothelial system and glia". The characteristic substances inside the extracellular matrix of this kind of tissue are the collagen, elastin and ground substance.
History of anatomy included Alessandro Achillini and Antonio Benivieni. Pathological anatomy Leonardo da Vinci (1452–1519) was trained in anatomy by Andrea del Verrocchio. In 1489 Leonardo began a series of anatomical drawings depicting the ideal human form. This work was carried out intermittently for over 2 decades. During this time he made use of his anatomical knowledge in his artwork, making many sketches of skeletal structures, muscles and organs of humans and other vertebrates that he dissected. Initially adopting an Aristotlean understanding of anatomy, he later studied Galen and adopted a more empirical approach, eventually abandoning Galen altogether and relying entirely on his
