What is the interventricular sulcus?

The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves that separates the ventricles of the heart, the other being the posterior interventricular sulcus. The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin.

Similarly one may ask, what does the anterior interventricular sulcus contain?

anatomy of heart 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 atrioventricular sulcus? 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). The other, the anterior interventricular sulcus, runs along the line between the…

Then, what is the function of the blood vessels in the anterior interventricular sulcus?

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.

What is the posterior interventricular sulcus?

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 interventricular sulcus located?

The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves that separates the ventricles of the heart, the other being the posterior interventricular sulcus. The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin.

Where is the coronary sulcus located?

Major coronary blood vessels are located in these sulci. The deep coronary sulcus is located between the atria and ventricles. Located between the left and right ventricles are two additional sulci that are not as deep as the coronary sulcus.

Which coronary artery is most commonly blocked?

LAD

Where is the base of the heart?

The heart is located in the middle of the thorax, with the apex facing toward the left and inferiorly, at the level of the 5th intercostal space. The base of the heart is the posterior part of the heart. The heart has four surfaces: Sternocostal surface: The anterior portion formed mostly by the right ventricle.

What structure separates the right and left ventricles?

septum

What is the function of the fluid that fills the pericardial sac?

WHAT IS THE FUNCTION OF THE FLUID THAT FILLS THE PERICARDIAL SAC? FLUID IN THE PERICARDIAL SAC ALLOWS THE HEART TO BEAT IN A RELATIVELY FRICTIONLESS ENVIRONMENT. TO REDUCE FRICTION DURING HEART ACTIVITY.

Where does the coronary sinus receives blood from?

Function. The coronary sinus receives blood mainly from the small, middle, great and oblique cardiac veins. It also receives blood from the left marginal vein and the left posterior ventricular vein. It drains into the right atrium.

How many pulmonary veins are there?

four pulmonary veins

What is the function of middle cardiac vein?

The middle cardiac vein or posterior interventricular vein is a vein of the heart which accompanies the posterior interventricular artery. It courses in the posterior interventricular groove and drains directly into the coronary sinus close to it's termination.

What are the grooves of the heart?

The heart is a hollow structure. On the interior, it is divided into four chambers. These divisions create grooves on the surface of the heart – these are known as sulci. The coronary sulcus (or atrioventricular groove) runs transversely around the heart – it represents the wall dividing the atria from the ventricles.

Where is the apex of the heart located?

The apex of the heart is a conical area created by left ventricle. It's directed downwards and forwards, and to the left. It is located at the level of the 5th left intercostal space, 3.5 inches (9 cm) from the midline and just medial to the midclavicular line.

What is the great cardiac vein?

The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.

What is the function of the anterior interventricular artery?

Within the groove, the anterior interventricular artery passes around the inferior border of the heart. On the inferior surface of the heart it anastomoses with the posterior interventricular branch of the right coronary artery. The anterior interventricular artery supplies the: left ventricle.

Which chambers are at the apex end of the heart?

At the bottom of the heart is the bluntly pointed free end, or apex. The two atrial chambers are to the left and right of the vessels near the base of the heart. The ventricles are attached beneath the atria and form most of the body of the heart to the apex.

How many cardiac veins are there?

Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.

Which vein travels with the posterior interventricular artery?

middle cardiac vein

What is in the coronary sulcus?

The atria are separated from the ventricles by the coronary sulcus (auriculoventriculargroove); this contains the trunks of the nutrient vessels of the heart, and is deficient in front, where it is crossed by the root of the pulmonary artery.

How many coronary sulcus are there?

two coronary sulci

What is Fossa Ovalis?

The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between right and left atrium. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development.
