The central tendon of the diaphragm, a vital structure in human anatomy, is often referred to by varying synonyms that highlight its significance and location. One synonym commonly used is the "diaphragmatic central tendon". This term emphasizes the central positioning of the tendon within the diaphragm muscle. Another synonym frequently employed is the "medial tendon of the diaphragm", which underscores its location at the midpoint of the diaphragm. Additionally, it is sometimes referred to as the "central aponeurosis of the diaphragm", emphasizing its fibrous composition. Regardless of the synonym used, the central tendon of the diaphragm serves a pivotal role in regulating respiration and separating the thoracic and abdominal cavities.
