Term
Chordae Tendeneae
Definition
atteched to distal edges of AV valve leaflets
Term
Papillary Muscles
Definition
coned-shaped muscular pillars that contract when the ventricles contract and support the chordae tendeneae of the AV valve leaflets by preventing the valves from opening into the atria.
Term
AV valve tissue make-up
Definition
cologen, fibrenogen, and connective tissue
Term

(skeletal) supports AV valves at base

Commissures
Definition
where the AV valve leaflets meet at the distal end near the annulus

separates the smooth from the trebeculated portion of the inter-RA(proximal to the oriface of the SVC)
Term
Sulcus Terminalis
Definition
anatomical landmark that designates the Nodal Artery; proximal to the Right Auricle and distal to the Right Superior Pulmonary Vein; the external counterpart of the Crista Terminalis
Term
Trebeculation
Definition
course bundles of muscles
Term
Moderator Band
Definition
extends from the Septal Band to the Anterior Papillary Muscle in the RV; it is important because it carries part of the right bundle branch of the AV bundle of the conduction system of the heart to the anterior papillary muscle. This shortcut across the chamber of the ventricle seems to facilitate conduction time, allowing coordinated contraction of the anterior papillary muscle.
Term
Septal Band
Definition
Muscular continuation of supra-ventricular crest from which the media (septal) papillary muscle of tricuspid valve arises.
Term
Pariteal Band
Definition
a muscular band around the superior portion of the tricuspid valve that aids in contraction of the base of the RV.
Term
azygos vein
Definition
transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava vein
Term
lower esophageal veins
Definition
drains blood from the esophagus and thyroid to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck
Term
Bronchial Veins
Definition
small vessels that return blood from the larger bronchi and structures at the roots of the lungs. The right side drains into the azygos vein, while the left side drains into the left superior intercostal vein or the accessory hemiazygos vein
Term
