From Wikipedia, the free encyclopedia. Interventricular groove may refer to: Anterior interventricular sulcus, one of two grooves that separates the ventricles of the heart, near the left margin. Posterior interventricular sulcus, one of the two grooves that separates the ventricles of the heart, near the right margin.
What is found within the interventricular groove?
The interventricular groove runs anteriorly toward the apex and contains the great cardiac vein. Posteriorly, it continues along the inferior surface of the heart toward the right margin and contains the middle cardiac vein. The heart has five surfaces, anterior, posterior, inferior, and a right and left.
What is the function of interventricular groove?
role in cardiovascular system Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart. There are two grooves on the external surface of the heart.
Where is the interventricular groove located?
A furrow on the anterior and posterior surfaces of the heart that marks the boundary between the right and left ventricles; it runs approximately perpendicular to the atrioventricular groove.
What is atrioventricular groove?
In human cardiovascular system: External surface of the heart. One, the atrioventricular groove, is along the line where the right atrium and the right ventricle meet; it contains a branch of the right coronary artery (the coronary arteries deliver blood to the heart muscle).
What structures are found in the interventricular sulcus?
The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein. Anterior interventricular sulcus
- left ventricle.
- anterior interventricular sulcus.
- right ventricle.
- conus arteriosus.
- pulmonary artery.
- Ligamentum arteriosum.
- aortic arch.
- brachiocephalic artery.
What does anterior interventricular sulcus contain?
The other, the anterior interventricular sulcus, runs along the line between the right and left ventricles and contains a branch of the left coronary artery.
What is the function of the anterior interventricular artery?
It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system. Hence, blockage of this artery due to coronary artery disease can lead to impairment or death (infarction) of the conducting system.
What is the function of the interventricular septum quizlet?
Interventricular septum is a muscular wall that separates right and left ventricles. It prevents the mixing of oxygenated and deoxygenated blood.
What is the function of posterior interventricular artery?
The origin of the posterior interventricular artery accounts for the termed dominance of the heart. The main function of the posterior interventricular artery is to supply a small posterior aspect of the interventricular septum [ 7] and the posterior aspect of the right ventricle .
Where is the anterior interventricular sulcus located?
The ventricles of the heart are separated by two grooves, one of which, the anterior longitudinal sulcus (or anterior interventricular sulcus), is situated on the sternocostal surface of the heart, close to its left margin.
Where is the anterior interventricular artery located?
The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.
Where is the posterior interventricular sulcus located?
The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves that separates the ventricles of the heart and is on the diaphragmatic surface of the heart near the right margin.
Where is the AV groove of the left circumflex?
The atrioventricular groove is identified inferior to the coronary sinus, and a segment of the circumflex vessel is exposed in the epicardial fat beneath the coronary sinus. The segment lies some distance up and beneath the coronary sinus itself.
What vein runs along the AV groove?
The small cardiac vein runs along the right AV groove downward toward the crux, where it subsequently empties into the coronary sinus. Some of the anterior cardiac veins drain directly into the right atrium.
What runs in the coronary groove?
The left anterior descending artery and the great cardiac vein run in the anterior interventricular groove; the posterior descending artery and the middle cardiac vein run in the posterior interventricular groove.
