What is the cause of staircase phenomenon in case of cardiac muscle?

The staircase phenomenon occurs because of qiuck succession of stimuli with a time interval of only about 2 s between the stimuli. During this period,the beneficial effect is produced which facilitates the force of successive contraction. So there is a gradual increase in the force of contraction.

What effect does hyperkalemia have on cardiac muscle?
it cause cardic arrest
What causes skeletal and cardiac muscles to appear striated?
The myofibres cause skeletal and cardiac muscles to appear striated because they are cyndrical and long, extending across the entire surface of the muscle.
How is cardiac muscle similar to smooth muscle?
Cardiac muscle tissue, like skeletal and smooth muscle tissue, can undergo hypertrophy.Unlike both smooth and skeletal muscle, cardiac muscles have cells that branch.
How do you get team galactic out of the way of the staircase?
uhh, which staircase cause there is many?
Where are your cardiac muscles located?
Firstly, you need to realise that the heart itself is considered a muscle that contracts to pump blood around your body. More specifically, the heart is referred to as a myogenic muscular organ, which pretty much means an organ that is also a muscle. If you are meaning cardiac muscle as one of the three types of muscle, it is located in the heart, primarily on the myocardium. These cardiac muscles cause the heart to contract (undergo systole) and force blood through the atria and ventricles.
Can Raynaud's phenomenon cause Secondary vasculitis?
Raynaud's phenomenon can cause Secondary vasculitis
What happens in a heart when an action potential is generated in the SA node?
It simulates the node, which then sends impulses to the AV node, which disperses these impulses through the cardiac muscle to cause a cardiac cycle (rhythmic beating and relaxing of atria and ventricles)
What are the three jobs that muscle cell have in the body?
Cardiac Muscle Cells which cause the heart to Beat, Skeletal Muscle Cell forms tissues that help move bones, Smooth Muscle Cells forms organs that help move food in the digestive system, It also lines blood vessels and the airways of the lungs
What is idiopathic cardiomyopathy?
Hypertrophic cardiomyopathy (HE stain) is a disease that is characterized by the abnormal thickening of the heart muscle, which makes it difficult for the heart to pump blood.
Which mineral affects muscle contraction and cardiac function as well as human bones and teeth?
Calcium is absolutely necessary for muscle contraction (both skeletal and cardiac) and for bone and teeth formation. 99% of the calcium in your body is stored in your teeth and bones. It is thought that you should drink as much as 6 glasses of milk a day. That much will not cause gall stones as once was thought.
