| 释义 | septum noun[ C ] anatomy specializeduk /ˈsep.təm/ us /ˈsep.təm/pluralseptauk /-tə/ a thin part dividing tissues or spaces in an organ such as the nose or heart: （身体器官如鼻子或心脏内的）隔，隔板，隔膜 the nasal septum鼻中隔 Substances & structures in the body abductor accessorius ACL actin adductor fundus funiculus fusiform glomerular glomerulus myosin navicular neuroendocrine neurohormonal neurohormone tendinous tendinum tendo tensor Th Examples of septumseptum When a remnant of the interventricular membranous septum is also present, the so-called membranous flap, it lies immediately on top of the atrioventricular bundle. The funnel consisted of myocardium that formed a continuity between the right wall of the atrioventricular canal and the ventricular septum. The membranous atrioventricular septum can itself also very rarely be deficient in isolation. At this stage, the wider curved end of the baffle is brought down onto the remnant of the atrial septum between the atrioventricular valves. The distinction between the two entities depends on whether the atrial septum walls off the left atrium from the atrioventricular junction. The interatrial septum bulged to the left, contributing further to the huge right atrium. The malaligned atrial septum was widely excised to reveal a small left atrium receiving the pulmonary venous orifices and a tiny atrial appendage. The angiosarcoma, due to its invasive nature, required extensive resection, after which pericardial patches were needed to reconstruct the right atrium and the septum. Both traps in the fourth chambers were baited with hexane-treated septa. There is continuity of the leaflets of the aortic and pulmonary valves because of absence of the outlet septum. Small-to-moderate sized muscular defects in the apical trabecular septum often close by growth and hypertrophy of the muscular septum. The muscular outlet septum, and the "septal" components of the subpulmonary infundibulum, were absent. Six of the seven patients had complete deficiency of the muscular outlet septum, with the defect extending to the perimembranous area. Such complete absence of the muscular outlet septum was not present in any of the patients without the deletion. There is posterior deviation of the outlet septum giving rise to muscular subpulmonary stenosis. These examples are from corpora and from sources on the web.
