A fascia (, ; plural fasciae ; adjective fascial; from Latin: "band") is a band or sheet of connective tissue fibers, primarily collagen, that forms beneath the skin to attach, stabilize, enclose, and separate muscles and other internal organs.〔 Fasciae are classified according to their distinct layers as in superficial fascia, deep (or muscle) fascia, visceral and parietal fascia, and by their functions and anatomical location. Like ligaments, aponeuroses, and tendons, fasciae are made up of fibrous connective tissue containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of pull. Fasciae are consequently flexible structures able to resist great unidirectional tension forces until the wavy pattern of fibers has been straightened out by the pulling force. These collagen fibers are produced by the fibroblasts located within the fascia. Fasciae are similar to ligaments and tendons as they have collagen as their major component. They differ in their location and function: ligaments join one bone to another bone, tendons join muscle to bone and fasciae surround muscles or other structures. ==Structure== There exists some controversy about what structures are considered "fascia", and how fascia should be classified.〔 〕 The two most common systems are: * The one specified in the 1983 edition of Nomina Anatomica (NA 1983) * The one specified in the 1997 edition of Terminologia Anatomica (TA 1997) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「fascia」の詳細全文を読む スポンサード リンク
