atrio-ventricular canal atrial canal AV canal AVC ependymal canal canalis atrioventricularis |
|
| Definitions |
The part of the heart connecting the atrium to the cardiac ventricle[ZFA]. In the developing heart, the constriction between the atrium and ventricle constitutes the atrial canal, and indicates the site of the future atrioventricular valves[WP]. |

| homology_notes |
The heart is the first organ to form and function in a vertebrate. (...) Septation of the AV canal is initiated with the formation of inferior and superior endocardial cushions in response to signaling from the overlying myocardium. (...) Analysis of zebrafish mutants with cardiovascular defects uncovered a previously unexpected level of conservation between zebrafish and human cardiovascular physiology.[uncertain][VHOG] |
