Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves. Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. (Some cells can make the heart beat on its own.) This doesn't occur in any other type of muscle tissue. This ability can keep the heart pumping even under disease conditions.

What type of muscle is found only in the walls of the heart?
Cardiac muscle forms the muscular wall of the heart. Cardiac muscle is involuntary muscle.
What type of cells are found in the heart?
"I am not sure of names but i know that many cells make up the heart! Try to look on the Internet for your answer. Hope this helped a bit :)" You got to be kidding me... that wasn't helpful at all, but whatever. In the heart you can find: - Myocardiocytes - those are the cells performing the rhytmic contraction of the whole heart. - Endothelial cells - those are the supporting epithelial cells, insulating the chambers of the heart and the veins.
What type of of muscle is found only in the heart?
Cardiac muscle is found only in the heart. Cardiac muscle contains the proteins actin and myosin. All the other muscles are smooth or skeletal.
Can the heart contain smooth muscle?
No, they are not. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. Cardiac muscle, like other muscles, can contract, but some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Meaning that some of the cells can beat on their own without any nerve stimulation.
What are heart enzymes?
Enzymes of the heart.ANSWER 2 Different Cardiac EnzymesThe heart is a muscular pump. When a person experiences a heart attack, a portion of the heart muscle is damaged, causing symptoms such as shortness of breath, chest pain that can radiate, nausea, vomiting, dizziness and sweating. One way of determining whether these symptoms are the result of actual heart dysfunction or heart attack is through blood tests that evaluate the cardiac enzymes. When the heart muscle is damaged, it releases these cardiac enzymes into the bloodstream. When a blood test measures increased cardiac enzymes, it is an indicator that actual damage has resulted.Creatinine PhosphokinaseAccording to the American Heart Association, the most common cardiac enzyme to be tested when a heart attack is suspected is creatinine phosphokinase (CPK). This enzyme is normally present in small amounts in the blood and is released by all muscle tissue in the body--skeletal, cardiac and smooth muscle. When CPK is elevated, it indicates muscle damage and further tests can be ordered. Often, when a patient enters a medical facility complaining of heart attack symptoms, elevated CPK may be the only indicator that a heart attack has actually occurred. Sometimes CPK will not read high in the blood until 24 hours after the heart attack, so careful monitoring for a period of time is required. CPK-MBCPK-MB is a fractional piece of creatinine phosphokinase. Although CPK is released from all muscle tissue in the body, CPK-MB is released only from damaged heart tissue, so it is much more accurate in determining whether a heart attack has occurred. CPK-MB is diagnostic for a heart attack even in the presence of a normal EKG. CPK-MB may not be elevated in the blood until 12 to 24 hours after a heart attack. Increased accuracy in diagnosis may be found by repeating the CPK-MB blood test multiple times over the first 24 hours, looking for changes in levels. TroponinsTroponins, proteins found in muscle tissue, help modulate actin and myosin, which are responsible for muscle contraction. Some very specific troponins have been identified as occurring only in the heart muscle, specifically Troponin T and Troponin I. These can be tested for and measured. These troponins are normally present in very low quantities in the blood. When elevated, they can indicate even very minor heart tissue damage that may not show up with a CPK test. Troponin typically shows up in the blood as elevated within 12 hours after a heart attack. By measuring Troponin and CPK, it is possible to diagnose a heart attack even when other tests may be negative.
Are tendons primarily made up of cardiac tissue?
No, only the heart is made up of cardiac tissue.
What type of muscle is found only in the walls of the heart?
Cardiac muscle forms the muscular wall of the heart. Cardiac muscle is involuntary muscle.
What muscle tissue moves the heart?
If you mean what kind of muscle tissues it is a special tissue found only in the heart called cardiac muscle tissue. It sometimes referred to by professionals as myocardium.
What muscle is only found in the walls of the heart?
cardiac muscle tissue
What kind of tissue is the Circulatory System made up of?
the answer is cardiac tissue. this type of tissue is only found in the heart.
Why couldn't your heart have only cardiac tissue?
Your heart could not have only cardiac tissue because the different types of tissues (connective, fibrous, muscle, etc.) all perform certain functions and also work together.
Does your heart have anything to do with the muscular system?
Yes, the heart itself is mostly made of muscle, the cardiac muscle, plus connective tissue. Cardiac Muscle is only found in the heart.
Does the heart have anything to do with the muscular system?

What is made out of cardiac muscle in the circulatory system?
The heart is the only thing in the body that is made up of the specialized tissue in cardiac muscle
What are the muscles only found in your heart?
The only muscle found in the heart is cardiac muscle.
Involuntary muscle tissue found in the heart?
Cardiac muscle tissue is the involuntary muscle tissue found in the heart. It is striated and contracts to pump blood throughout the body. This type of muscle is highly specialized and functions to maintain the continuous beating of the heart.
Why does the heart has different types of tissues?
The heart does consist or atria, ventricles, etc. but these are the gross, anatomical divisions of the heart. In asking about the kinds of tissues contained in the heart, we have to think of the cells found there. The heart obviously contains cardiac muscle, it is practically the only site where it is found, except for the transitions between the heart and the large vessels arising from it. Cardiac muscle consist of the typical cardiac muscle cells, which are di-nucleated, branched cells which connect to each other at intercalated disks, making the heart muscle a functional syncitium. In addition, the heart contains modified cardiac muscle cells called Purkinje cells. These cells transmit electrical impulses to the ventricles, to stimulate them to contract. The heart also contains connective tissue, serving various purposes, such as binding groups of cardiac muscle cells into fascicles, etc.
