CONTRACTION
desmosomes
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).
The two types of tissue repair are regeneration, where damaged tissue is replaced with new functional tissue, and fibrosis, where damaged tissue is replaced with scar tissue made of collagen fibers. Regeneration is ideal as it restores normal tissue function, while fibrosis can lead to loss of function depending on the extent of scarring.
gap junctions. These specialized connections allow for rapid and coordinated depolarization of cardiac muscle cells, ensuring efficient contraction of the heart.
Myocardial infarction (MI) can disrupt the normal cardiac cycle by causing damage to the heart muscle, leading to impaired contraction and relaxation. This can result in diminished cardiac output, arrhythmias, and heart failure. The severity of these effects depends on the location and extent of the heart damage.

because the force of myocardial contraction weakens
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.
Myocardial systole means heart contraction.
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).
Cardiac contractility is the force of contraction possible for any given length of the cardiac muscle. It is related to the intracellular calcium levels.
