What is the thin filament of the myocardial cell?

The thin filament of a myocardial cell is composed primarily of actin, tropomyosin, and troponin proteins. These proteins play a crucial role in regulating the contraction and relaxation of the heart muscle by interacting with the thick filament during the process of muscle contraction.

What does stretching a myocardial cell cause the cell to do?

Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).


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.
