| Preferred Name | sinoatrial node | |
| Synonyms |
nodus sinuatrialis sinuatrial nodal muscle tissue SA node Koch's node node of Keith-Flack sinus node sinuatrial node cardiac pacemaker SA nodal muscle tissue sinoatrial node sinu-atrial node sinus node of Keith and Flack |
|
| Definitions |
The part of the cardiac conduction system that controls the timing of heart muscle contraction. It relays electrical signals to the AV node[GO]. Subdivision of conducting system of heart at the junction of the right atrium and the superior vena cava, around the sinoatrial nodal branch of right coronary artery and is continuous with the internodal tract[FMA]. WP:Heart states: "The SA node is found in all amniotes but not in more primitive vertebrates. In these animals, the muscles of the heart are relatively continuous and the sinus venosus coordinates the beat which passes in a wave through the remaining chambers. Indeed, since the sinus venosus is incorporated into the right atrium in amniotes, it is likely homologous with the SA node. In teleosts, with their vestigial sinus venosus, the main centre of coordination is, instead, in the atrium.". Note however that ZFA has SA node. |
