<prompt> Slow waves are generated by:Myentric neuronsSmooth muscleInterstitial cells of cajalParasympathetic neurons  <response>: ANS. C Slow waves are the oscillating membrane potential between -60 and -40 mv in smooth muscle of GI smooth muscle. They are also called basal electric rhythm BER BER is maximum at duodenum 12minute and minimum at ileum 2min Acetyl choline increases BER and adrenergic stimulation decreases BER Another topic asked in last November AIIMS 2016 was regarding migratory motor complex. Migratory motor complex in the gut are initiated by motilin. The contractions migrate at a rate of 5 cmmin and also occur at intervals of approximately 90 min. Migrating motor complex MMC appear during fasting and are inhibited by meal. When a meal is taken, motilin is supressed and MMC is abolished. Gastric secretion, bile flow and pancreatic secretion increase during each MMC.
