Three major adaptations, or 'novel cardiac components', that were not present in the ancestor chordate heart tube can be distinguished in the lower vertebrate heart: the atrium, ventricle, and possibly the muscular sinus venosus. Furthermore, within the ventricular component a compact outer myocardial component and an interiorly localized extensive trabecular component can be distinguished. The specific activation of the ventricle adds to its complexity as follows. The depolarizing impulse travels rapidly from the atrioventricular node toward the apex and then toward the conal region, achieving activation from apex to base.[uncertain][VHOG] |
