The action of ANS-related drugs on smooth muscle Introduction In the following experiment‚ the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum. A series of dilutions
