The stomach empties at a rate proportional to the volume of chyme in it. This reflexive emptying of the stomach is based in part on activation stretch-activated channels in the plasma membrane of smooth muscle cells that help mediate excitation-contraction coupling in the cells. The ions that flow through this channel are most likely ________ ions.
Smooth muscle contract spontaneously with the help of ionic channel dynamics or pacemakers cells interstitial cells of Cajal produce rhythmic contractions in the gut special . contraction, as well as relaxation, can be formed by a number of physiochemical agents e.g., hormones, drugs, neurotransmitters i.e from the autonomic nervous system.Stretch-activated cation channels occur in smooth muscle and promote E-C coupling by depolarizing myocytes and by mediating sufficient Ca2+ flux to effect contraction.
