Motor activity of the stomach in V. griseus consists of contractions which follow the rhythm of 7-10 movements per 15 min. In contrast to tortoises, no periodic hunger activity of the stomach was observed in the lizard. Subcutaneous injection of 0.6% NaCl solution does not affect contractile activity of stomach muscles. Pilocarpine in a dose 100 microgram/kg of body weight did not change the gastrogram, doses 500 and 1,000 microgram increased the frequency and the amplitude of contractions. Atropine in a low dose (100 microgram) did not affect stomach movements. Doses 500, 1,000 and 2,000 microgram induced biphasic response. Sunflower-seed oil (10 ml) decreased twofold the frequency and the amplitude of contractions within 45-60 min.
沙蜥胃的运动活动由收缩组成，其收缩频率为每15分钟7 - 10次。与乌龟不同，在蜥蜴中未观察到胃的周期性饥饿活动。皮下注射0.6%的氯化钠溶液不影响胃肌肉的收缩活动。剂量为100微克/千克体重的毛果芸香碱不会改变胃电图，剂量为500和1000微克时会增加收缩频率和幅度。低剂量（100微克）的阿托品不影响胃的运动。剂量为500、1000和2000微克时会引起双相反应。葵花籽油（10毫升）在45 - 60分钟内使收缩频率和幅度降低了两倍。
