The anterior cardiac veins are a group of parallel coronary veins that course over the anterior surface of the right ventricle, draining it and entering directly into the right atrium. They may occasionally drain into the small cardiac vein.
Where does the anterior cardiac vein drain directly?
right atrium The anterior cardiac veins drain directly into the right atrium. There are also tiny veins in the walls of each of the chambers called the thebesian veins or venate cordis minimi, which drain directly into their own relevant chamber.
What are the 3 cardiac veins?
cardiac veins which drain into the coronary sinus:
- great cardiac vein.
- middle cardiac vein.
- small cardiac vein.
- posterior vein of the left ventricle.
- vein of Marshall (oblique vein of the left atrium)
Where does anterior cardiac vein open?
right atrium The anterior cardiac veins (or anterior veins of right ventricle) comprise a variable number of small vessels, usually between two and five, which collect blood from the front of the right ventricle and open into the right atrium; the right marginal vein frequently opens into the right atrium, and is therefore …
What is the function of anterior cardiac vein?
The function of the anterior cardiac veins is to drain the upper anterior portion of the myocardium of the right ventricle. These veins empty directly into the right atrium, unlike the majority of the cardiac veins that empty into the coronary sinus.
What do cardiac veins do?
The primary physiological function of the coronary veins is to carry deoxygenated blood from the myocardium and empty them into the chambers of the heart.
Where 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.
Where are cardiac veins located?
Near the left atrium, the great cardiac vein veers to the left and enters the coronary sulcus (= between the left atrium and ventricle), where it extends to the back side of the heart. One or more left marginal veins typically merge with the great cardiac vein as it traverses the lateral ventricular wall.
Which cardiac vein directly enters the right atrium?
coronary sinus The middle cardiac vein drains into the coronary sinus or directly into the right atrium [4]. The small cardiac vein, also known as the right cardiac vein [12], commonly drains the inferior and lateral wall of the right ventricle.
What is the anterior 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 are the four vessels of the heart?
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …
What is the myocardium?
The muscle layer of the heart is termed the myocardium and is made up of cardiomyocytes. The myocardium is found in the walls of all four chambers of the heart, though it is thicker in the ventricles and thinner in the atria.
Where are smallest cardiac veins open?
The openings of the smallest cardiac veins are located in the endocardium. Here the smallest cardiac veins return blood into the heart chambers from the capillary bed in the muscular cardiac wall, enabling a form of collateral circulation unique to the heart.
What artery accompanies the great cardiac vein?
Cardiac Veins The great cardiac vein continues its course in the left anterior AV groove along with the LCx artery (see Fig. 50.3A).
Do all cardiac veins drain into the coronary sinus?
The coronary sinus receives drainage from most epicardial ventricular veins, including the oblique vein of the left atrium (and other left and right atrial veins), the great cardiac vein, the posterior vein of the left ventricle, the left marginal vein, and the posterior interventricular vein.
What is another name for the great cardiac vein?
Anatomical terminology The great cardiac vein (left coronary vein) begins at the apex of the heart and ascends along the anterior longitudinal sulcus to the base of the ventricles.
What is tendon of Todaro?
A fibrous structure formed by the junction of the eustachian valve and the thebesian valve (valves of the inferior caval vein and coronary sinus, respectively).
What is Infundibulum of heart?
The infundibulum (also known as conus arteriosus) is a conical pouch formed from the upper and left angle of the right ventricle in the chordate heart, from which the pulmonary trunk arises. It develops from the bulbus cordis. … The wall of the infundibulum is smooth.
What receives blood from cardiac veins?
The right and left sides of the heart are further divided into: Two atria – top chambers, which receive blood from the veins and. Two ventricles – bottom chambers, which pump blood into the arteries.
Where is the posterior cardiac vein?
The posterior vein of the left ventricle is a vein of the heart which courses over the inferior wall of the left ventricle and drains into the coronary sinus to the left of where the middle cardiac vein drains into the sinus. It drains, not unsurprisingly, the inferior wall of the left ventricle.
Where is the anterior interventricular artery?
left coronary artery 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.
What drains the heart?
The right and left sides of the heart work together Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
Which cardiac vein travels with the left marginal artery?
| Left marginal artery | |
|---|---|
| Vein | left marginal vein |
| Supplies | left ventricle |
| Identifiers | |
| Latin | ramus marginalis sinister arteriae coronariae sinistrae |
What is Koch’s triangle?
Koch’s triangle, named after the German pathologist and cardiologist Walter Karl Koch, is an anatomical area located in the superficial paraseptal endocardium of the right atrium, which its boundaries are the coronary sinus orifice, tendon of Todaro, and septal leaflet of the right atrioventricular valve.
Why is right atrium called First Chamber?
Right Atrium. The right atrium is the first chamber of the heart that the blood comes into contact with as it returns from the systemic circulation, and from the blood supply to the heart. The blood entering this chamber is deoxygenated.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
