There are two types of cardiac muscle cells, those that contract and those that set the rhythm. Both are basically the same cell.

What are individual muscle cells termed?
Another name is myocyte. It is formed from a myoblast. There are three types: smooth, striated and cardiac cells.
Where are myocytes found?
in the heart
What are the components of the striations in striated and cardiac muscles?
Yes, they are. While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles. Anatomically, the muscle fibers are typically branched like a tree branch. In addition, cardiac muscle fibers connect to other cardiac muscle fibers through intercalcated discs and form the appearance of a syncytium (continuous cellular material). These intercalcated discs, which appear as irregularly-spaced dark bands between myocytes (muscle cells), are a unique feature of cardiac muscle .
Which two muscle types are controlled involuntarily?
Visceral muscles, which are under involuntary control, come in two forms. They are the smooth muscle tissue and cardiac muscle tissue, found only in the heart.
What are the two microscopic features of cardiac cells that help distinguish them from other types of muscle cells?
Cardiac muscles are found solely in the heart. The involuntary muscles making up the heart don't suffer fatigue like the regular muscles do.
What is the sa node made of?
cardiac myocytes....
What is a heart made up of?
Cardiac myocytes and connective tissue
How does the structure of cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart?
The structure of the heart is very complex. Cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart make up part of this very complex system
What condition is characterized by rapid uncoordinated contractions of cardiac myocytes?
Contraction Band Necrosis
What cells make up the myocardium?
Most of the myocardium is composed of cardiac myocytes.
Why does the heart has somethimg to do with the muscles?
Because it`s made of muscle. Cardiac muscle. Involuntary striated myocytes.
Which two types are involuntary?
Skeletal and cardiac
How is heart muscle different from striated muscle?
Cardiac muscle is a type of involuntary striated muscle found in the walls of the heart, specifically the myocardium. Cardiac muscle cells are known as cardiac myocytes (or cardiomyocytes). Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle are sometimes seen as intermediate between these two other types in terms of appearance, structure, metabolism, excitation-coupling and mechanism of contraction. Cardiac muscle shares similarities with skeletal muscle with regard to its striated appearance and contraction, with both differing significantly from smooth muscle cells.Source: http:/en.wikipedia.org/wiki/Cardiac_muscle
What are two types of muscle fiber?
cardiac and smooth
What are the two kinds of involuntary muscles?
Which two types of muscles are involuntary?
What are the two types of shock that diabetics go into?
septic and cardiac
Types of muscle are involuntary?
Of the three types of muscle, the two that are involuntary are cardiac muscle and smooth muscle.
