Explanation:
Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.
Given what we know, we can confirm that the amount of tension in the ventricular myocardium immediately before it contracts is called the preload.
<h3>What is ventricular myocardium tension?</h3>
The ventricular myocardium refers to the cells that make up the ventricles of the heart. These would be the lower chambers in charge of ejecting the blood from the heart so that it may circulate. The tension we are referring to is caused by the stretching of these ventricles as they fill with blood and are preparing to contract.
Therefore, we can confirm that the preload is the name given to describe the amount of tension in the ventricular myocardium immediately before it contracts.
