WebAug 18, 2003 · Abstract. Smooth muscle is responsible for the contractility of hollow organs such as blood vessels, the gastrointestinal (GI) tract, gall bladder, bladder, and uterus. The structure of smooth muscle differs greatly from that of skeletal muscle. Smooth muscle can develop isometric force per cross-sectional area that is equal to that of … WebApr 10, 2024 · Iris Sphincter. Sphincters are circular muscles that open and close passages in the body to regulate the flow of substances, such as bile, urine, and feces, through the body. 1 Although many are found in the gastrointestinal (GI) tract, there are also sphincters in the urinary tract and blood vessels.

Smooth muscle cells in this … A slow-wave potential is a rhythmic electrophysiological event in the gastrointestinal tract. The normal conduction of slow waves is one of the key regulators of gastrointestinal motility. Slow waves are generated and propagated by a class of pacemaker cells called the interstitial cells of Cajal, which also act … See more In the human enteric nervous system, the slow-wave threshold is the slow-wave potential which must be reached before a slow wave can be propagated in gut wall smooth muscle. Slow waves themselves seldom cause any … See more Gastric slow waves occur at around 3 cycles-per-minute in humans and exhibit significance variances in both amplitudes and propagation velocities in the stomach due to the existence of a gradient of resting membrane potential gradient, interstitial cells of … See more garmin etrex touch 35 gps/glonass handheld
