What is myocardial contractility?
Cardiac contractility is the force of contraction possible for any given length of the cardiac muscle. It is related to the intracellular calcium levels.
Why does contractility of the cardiac muscle increase with increased filling?
It doesn't - "contractility" refers to the force generated at any given length of muscle. Therefore although the force of contraction does increase with filling, the contractility does not.The reason the force of contraction increases with filling is because filling stretches the heart muscles. Increased stretch causes an increase in force of contraction.Contractility changes because of changes in the level of intracellular calcium. This can be changed by things such as adrenalin (epinephrine), which increases contractility and β blockers, which decrease contractility.
Muscle tissue is characterized by its?
contractility
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
How does Myocardial Atrophy affect the heart?
Myocardial atrophy is a condition where the heart chambers decrease in size. The heart muscle atrophy or shrink because of cancer or other similar conditions.
What does the myo mean in myocardial?
myo is related to the word "muscle" myocardial refers to the heart muscle when someone says he had an "MI" (myocardial infarction) it means they had a heart attack - a lack of oxygen to the myocardium (heart muscle) The heart muscle has its own particular muscle that is found no where else in the body.
The contractility of heart muscle is its?
contraction strength at any given fiber length
There are two primary kinds of cells in the heart muscle These cells are the myocardial and electrical cells?
Myocardial cells lines the muscular walls of heart tissues (contractility and extensibility) Electrical cells is the conduction system of the heart. Can be conducted 3 ways: automaticity that generates action potential, excitability that responds to electrical impulses and conductivity transmit an electrical impulses from one cell to the next
What does myocardial mean?
It means "something" to do with the heart's muscle.
How can you use Myocardial in a sentence?
This means relating to the muscle tissue of the heart. Here are some sentences.He suffered a myocardial infarction, or heart attack.The disease caused myocardial damage.He has a myocardial infection.
What detects a muscle is under stretch and therefore initiates the inverse stretch flex?
the muscle spindle detects excessive stretch within the muscle , it response and makes the muscle contract
What muscle do you stretch when you do the flamingo stretch?
Quadrilateral
