The myocardium is located between the endocardium and the visceral layer of the serous membrane (epicardium) of the heart.

Where does blood enter the myocardium?

Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.

What causes weakening of the myocardium?

the muscles of the myocardium will weakened if there is valve prolapse and overload.

What is the coronary artery that nourish the myocardium?

The myocardium or heart muscle is nourished with oxygen-rich blood. The vessel that delivers the blood to the myocardium is called Coronary Arteries.

What does the myocardium do?

The myocardium is the thickest layer of the heart made of contractile muscles that pumps blood.

What blood vessels supply the myocardium?

The Coronary Artery takes oxygenated blood to the Myocardium

Is the right myocardium thicker than the left myocardium?

No, left is thicker than right.

Does the left ventricle have the thickest myocardium?

The Left ventricle is delicious, so the myocardium is sweeten it.

Trace the pathway of a drop of blood from the myocardium of the heart to the arm?

The myocardium does not have blood flow to the arm. The myocardium is the muscle of the heart and therefore only supplies blood to the heart.

Drains unoxygenated blood from the myocardium?

The coronary veins drain blood that is low in oxygen from the myocardium.

Which cell type makes up most of the myocardium?

Most of the myocardium is composed of cardiac myocytes.

The myocardium is the innermost layer of the heart true or false?

The myocardium is not the innermost layer of the heart, the endocardium is.

What is a hibernating myocardium?

Hibernating myocardium is a state when some segments of the myocardium exhibit abnormalities of contractile function. These abnormalities can be visualized with echocardiography, cardiac magnetic resonance imaging, nuclear medicine or ventriculography.

What is myocardium?

You have three layers in the heart. Outer layer is pericardium, middle layer is myocardium and inner layer is endocardium. Myocardium is composed mainly of cardiac muscles, connective tissue and blood vessels.

What is the middle layer of the heart called?

The mycardium

Which coronary artery supplies blood to the inferior myocardium?

The Right Coronary Artery supplies blood to the inferior myocardium

Myocardium is made of?

The myocardium is the middle layer of the walls of the heart, made of cardiac muscle, that contracts to push out blood.

What does O2 and nutrients deliever to the myocardium by what?

The myocardium receives its oxygen and nutrients from the coronary arteries, which lie on the outside of the heart.

What is myocarditis?

inflammation of the myocardium

Why does the myocardium receives it blood from coronary arteries and not from the cardiac chambers?

Myocardium is a type of muscle tissue. The reason why the myocardium receives its blood from coronary arteries and not from the cardiac chambers is because the blood from the cardiac chambers does not contain oxygen and nutrients.

What is bundle of His in cardiology?

The Bundle of His (Hiss) is a bundle of electrical nodes which allow the ventricles to contract. The bundle is located in the ventricular septum which divides the two ventricles and separates into the Perkinje fibers at the apex of the heart. It is located in the myocardium.

Where are the heart muscle cells found in your body?

The heart muscles cells are myocardium and they are located anterior to your vertebral column and posterior to your sternum in your upper left thorax.

What is the myocardium?

The myocardium consists mostly of cardiac muscle tissue that pumps blood out of the heart chambers. The muscle fibers are organized into planes.

Is the myocardium voluntary?

No, it is an involuntary muscle.

What treatment could be for myocardium infraction?

A Myocardium Infarction is a heart attack. The victim needs a hospital. CPR is the only first aid that can be provided.

What is the pacemaker for the entire myocardium?

The pacemaker of the entire myocardium is the: a) Atrioventricular junction b) bundle of his c) Purkinje fibers d) Sinoatrial node

Do the coronary blood flow supply the myocardium?

The coronary blood vessels supply the myocardium, or heart muscle. These are the heart's own systemic arteries.

What are the two types of cardiac tissue?

The myocardium and the specialized conduction system. The specialized conduction system most cells are depolarized spontaneously and the myocardium they are polarized.

What is the myocardium composed of?

Striated Muscle Fibers

What is the strongest valve in the heart?

The Muscular Myocardium

What is the heart layer containing intercalated disks?

The layer of the heart containing intercalated disks is the myocardium. Myocardium is one of the tissues of the heart that is made of cardiac muscles.

Where does myocardium receives its blood supply from?

The myocardium is the muscle of the heart. This muscle is supplied by arteries that branch off the aorta. So everytime the heart beats it pushes blood into the aorta and thus into systemic circulation and thus into the heart wall, as well. These arteries that supply the myocardium are called coronary arteries.

Functions of myocardium?

pumping blood and gives morphine

What is the pericardial membrane?

visceral pericardium,myocardium,endocardium

Name the muscle layer of the heart?

That would be the Myocardium

What are three membranes of the heart?

epicardium, myocardium and endocardium

How myocardium functions?

the thick middle layer of the heart

Describe how the nerve impulse travels in the heart?

The nerve impulse travels from the SA node to the cardiac muscle, myocardium. The myocardium contracts after stimulation. This contraction allows blood to be pumped.

Knot of modified myocardium that sets the pace of the heart?

The knot of modified myocardium that sets the pace of the heart is the sinoatrial (SA) node. The SA node is on the wall of the right atrium.

What is the thickness of the myocardium?

The thickness of the myocardium varies depending on location. the right side is about 4-5 mm thick. The left side can be as large as 8-15 mm thick.

What myocardium layers function in blood pumping?

You have three layers of heart. Outer is pericardium. Middle is myocardium. Inner is endocardium. The middle layer function in blood pumping, mainly.

What is an myocardium?

The myocardium is part of the most superficial layer of the heart. It is the middle of these three. The myocardium forms the bulk of the heart, and it consists mainly of cardiac muscle. This is the layer that sactually contracts. The myocardium's elongated, circularly and spirally arranged networks of cardiac mucle cells squeeze blood through the heart in the proper directions.
