In pulmonary arterial smooth muscle cells (PASMCs), an increase in the cytosolic Ca 2+ concentration ([Ca 2+] cyt) is involved in many physiological functions such as cell contraction, proliferation, migration, differentiation, and apoptosis [1, 2].On the other hand, chronic [Ca 2+] cyt increases cause vasoconstriction and vascular … WebThe exact rate depends upon the particular muscle and the temperature. Usually, the maximum tetanus tension is from 1.2 to 1.8 times greater than the maximum tension during a twitch. Within the muscle, many elastic structures, connected in series with the contractile elements, are stretched during contraction. coche electrico wiki
