WebbSlow waves unique feature of the electrical activity of gastrointestinal smooth muscle oscillating depolarization and repolarization of membrane potential of smooth muscle … WebbSome smooth muscle is self-excitatory. That is, action potentials arise within the smooth muscle cells themselves without an extrinsic stimulus. This is often associated with a …

WebbSmooth muscle fibers are about 200-500micrometers in length and about 2-10 micrometers in diameter. They are bundled together, about 1000 fibers in a bundle. In longitudinal muscles fibers, they extend down the intestinal tract and in circular muscle fibers, they extend around the gut. WebbA fundamental component of GI motility is an omnipresent bioelectrical activity termed slow waves, which are actively generated and propagated by the interstitial cells of Cajal (ICC) and smooth muscle cells (SMC). The role of ICC and/or SMC loss in disorders of GI motility is a significant area of on-going research. companies to invest in 202
