The coronary sinus drains through the posterior wall of right atrium at the orifice of the coronary sinus. [6] [1] This orifice is located at the posteroinferior aspect of the right atrium, just medial [1] and to the left of the orifice of inferior vena cava, [6] and between the inferior vena cava and the right atrioventricular orifice ...
The Coronoid process (from Greek korone, "like a crown") can refer to: . The coronoid process of the mandible, part of the ramus mandibulae of the mandible; The coronoid process of the ulna, a triangular eminence projecting forward from the upper and front part of the ulna
The coronoid process of the ulna is a triangular process projecting forward from the anterior proximal portion of the ulna. Structure
It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It is anatomically significant because the atrioventricular node is located at the apex of the triangle. The ...
The radial notch of the ulna (lesser sigmoid cavity) is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius. It is concave from before backward, and its prominent extremities serve for the attachment of the annular ligament.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
The sinoatrial node (also known as the sinuatrial node, SA node or sinus node) is an oval shaped region of special cardiac muscle in the upper back wall of the right atrium made up of cells known as pacemaker cells. The sinus node is approximately 15 mm long, 3 mm wide, and 1 mm thick, located directly below and to the side of the superior vena ...
