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.

Regarding this, what artery & vein are found in the posterior interventricular sulcus?

The middle cardiac vein starts at the posterior apex and drains upward in the posterior interventricular groove adjacent to the posterior descending coronary artery, usually entering the coronary sinus near its atrial ostium. In some cases, the middle cardiac vein has a separate opening into the right atrium.

One may also 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.

One may also ask, what are the anterior and posterior 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.

What is the function of the 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 interventricu- lar septum [7] and the posterior aspect of the right ventricle [6].

Where does the posterior interventricular artery come from?

The posterior interventricular artery of the heart is a branch of the right coronary artery. It branches off on the inferior surface of the heart within the atrioventricular groove. It enters the posteroinferior aspect of the interventricular groove and heads towards the apex of the heart.

Where is the posterior descending artery located?

The posterior descending artery (PDA) is also known as the posterior interventricular artery because it runs along the posterior interventricular sulcus to the apex of the heart. It is at the apex where it meets the left anterior descending artery that is traveling along the anterior surface of the heart.

What does the posterior descending artery supply blood to?

The posterior descending artery branch supplies blood to the inferior aspect of the heart. The LMCA supplies blood to the left side of the heart. The LAD provides blood to the anterior ventricular septum and the greater portion of the anterior portion of the left ventricle.

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.

What is LCX heart?

Anatomical terminology. The "LCX", or left circumflex artery (or circumflex artery, or circumflex branch of the left coronary artery) is an artery of the heart.

Where is the interventricular septum located?

Location: Medial wall of the left ventricle. This is the wall that borders septum between the left and right ventricle.

Which heart chamber receives oxygenated blood from the lungs?

left atrium

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.

Which coronary artery is most commonly blocked?

LAD

What structure separates the right and left ventricles?

septum

What is the function of right atrium?

Medical Definition of Right atrium Right atrium: The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.

What are the four chambers of the heart?

The heart has four chambers: two atria and two ventricles.

• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
• The right ventricle pumps the oxygen-poor blood to the lungs.
• The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

What is the right auricle?

Last Updated: Jun 11, 2015. The right auricle of the heart - also called the right atrial appendage (RAA) - is attached to the heart's right atrium. It's a small, cone-shaped pouch which comes out from the upper and front part of the atrium and overlaps the root of the aorta.

Where is the coronary sinus?

The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart's posterior (rear) surface between the left ventricle and left atrium.

What is the function of papillary muscles?

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).

Which one is the largest vein of the heart situated in the posterior part of coronary sulcus?

Coronary Sinus: The Great Coronary Vein empties into the Coronary Sinus, which in turn Empties into the Pulmonary Artery into the Right Atrium. The Coronary Sinus is located deep to the great vein, on the posterior wall of the Right Atrium.

Why is the left ventricle thicker than the right?

The ventricles of the heart have thicker muscular walls than the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as seen in the adjacent image. This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.
