Contractions, By Muscle Type - Smooth Muscle Contraction
... Contractions are initiated by the calcium-activated phosphorylation of myosin rather than calcium binding to troponin ... Contractions in vertebrate smooth muscle are initiated by agents that increase intracellular calcium ... process of depolarizing the sarcolemma and extracellular calcium entering through L-type calcium channels, and intracellular calcium release ...
Vasodilation - Examples and Individual Mechanisms
... relies on removing the stimulus for contraction, which depends on intracellular calcium ion concentrations and, consequently, phosphorylation of the light chain of the contractile ... vasodilation mainly works either by lowering intracellular calcium concentration or the dephosphorylation of myosin ... There are three main intracellular stimuli that can result in the vasodilation of blood vessels ...
Salivate - Stimulation
... to muscarinic receptors, specifically M3, and causes an increased intracellular calcium ion concentration (through the IP3/DAG second messenger system) ... Increased calcium causes vesicles within the cells to fuse with the apical cell membrane leading to secretion ... to α-adrenergic receptors will cause an increase in intracellular calcium levels leading to more fluid vs ...
