传统解剖教学认为心室肌分为浅、中、深3层,起于纤维环和左右纤维三角。而近年来,医学界出现了一个新的学说,即心肌带(ventricular myocardial band,VMB)理论[1~3],这个理论是由Torrent-Guasp提出的,该理论认为,心脏是一条由心肌纤维按螺旋缠绕形成的肌肉带所构成,这条心肌带起自肺动脉止于主动脉,分为2个环,4个段,其中心尖环分为降段和升段,基底环分为左室段和右室段,右室段构成右心室,其余3段构成左心室的
Traditional anatomical teaching that ventricular muscle is divided into shallow, middle and deep 3 layers, starting from the annulus and the fibrous triangle. In recent years, a new theory emerged in the medical field, namely, the theory of ventricular myocardial band (VMB) [1 ~ 3]. This theory was proposed by Torrent-Guasp. The theory is that the heart is a cardiac muscle composed of myocardial fibers According to the spiral wound muscle band formed, this heart muscle strips from the pulmonary artery stopped at the aorta, divided into 2 rings, 4 segments, including the apex ring is divided into descending and ascending segment, the basal ring is divided into left ventricular segment And right ventricular segment, right ventricular segment constitutes the right ventricle, the remaining three segments constitute the left ventricle
