Coupling in contractions

WebJul 7, 2024 · Cardiac contractility is regulated by changes in intracellular Ca concentration ([Ca 2+] i).Normal function requires that [Ca 2+] i be sufficiently high in systole and low in diastole. Much of the Ca needed for contraction comes from the sarcoplasmic reticulum and is released by the process of calcium-induced calcium release.

WebContractions tend to become stronger and more frequent as labor progresses. Such a contraction pattern would be denoted as regular uterine contractions, with a commentary on the frequency of the contractions (e.g., every 2-3 minutes). A normal contraction pattern is demonstrated in the picture above with contractions every 2-3 minutes.
