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]. [ ZFA : 0001315 http://en.wikipedia.org/wiki/Atrioventricular_canal https://github.com/obophenotype/uberon/issues/38 ]

This is just here as a test because I lose it

development notes
  • The right side of the AVC becomes the tricuspid valve whereas the left side of the AVC will become the bicuspid valve
external definition
  • The canal connecting the primitive atrium and ventricle in fishes and amniotes embryo. [TFD][VHOG]
external ontology notes
  • this is a lumen in EHDAA2
function notes
  • In the embryo, the atrioventricular canal delays the impulse from atrium to ventricle[PMID:22984480]
has exact synonym
  • atrial canal
  • AVC
  • AV canal
  • atrio-ventricular canal
has related synonym
  • ependymal canal
  • canalis atrioventricularis
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]
