All electrolytes are important to all muscles. In the cells there are sodium/potassium pumps that must be balanced. Some electrolytes are positive and some are negative. The balance (inside the cell vs. outside the cell) causes either contraction or relaxation.

Which electrolyte helps regulate cardiac impulse transmission and muscle contraction?
Potassium has the main direct effect on cardiac impulse transmission and muscle contraction. However, potassium (K+) and sodium (Na) have an inverse relationship; when one is increased the olther is decreased. In cardiac health, both must be balanced to effect homeostasis. This is why repeat electrolyte lab values and cardiac enzymes are so important in unstable cardiac patients.
Which type of muscle is the heart made of?
cardiac
Which electrolyte has a major role in muscle contraction and high or low levels of it can leacd to cardiac arrest?
potassium
What does the long refractory period observed in cardiac muscle mean?
it means that no matter what stimulus is applied the cardiac muscle will not be able to contract
What is the muscle tissue found in the heart?
Smooth cardiac muscle.
Why is it important for cardiac muscle cells to be branched and interconnected with other cardiac muscle cells?
so electrical impulses can be carried freely between cells
Muscle tissue that has intercalated disks?
cardiac muscle cells are joined by intercalated disks.
How do you describe the cardiac muscle?
Cardiac muscle is involuntary striated muscle. The cells of cardiac muscle have only one nucleus. The layer of the heart that contains cardiac muscle is called the myocardium.
What cells make up the myocardium?
Most of the myocardium is composed of cardiac myocytes.
Which tissue has intercalated discs?
cardiac muscles/involuntary muscle
What is potassiums function?
Potassium maintains proper fluid balance, nerve impulse function, muscle function, and cardiac function.
Is the Cardiac muscle appears striated and is completely voluntary?
cardiac muscle is striated cardiac muscle is not voluntary
