Abstract

The pigeon esophageal smooth muscle shows "spontaneous" rhythmic bursts of spikes with increasing discharge frequency from pharynx to crop. There are no slow waves. The changes of the electric pattern induced by pharmacological administrations of atropine, prostigmine, hexamethonium and by asphyxia suggest that the electric activity is myogenic in origin. The innervation plays a role in the control of this activity and it is essential for the functional polarization.

摘要

鸽子食管平滑肌呈现出“自发”的节律性锋电位爆发，从咽到嗉囊放电频率逐渐增加。没有慢波。通过给予阿托品、新斯的明、六甲铵以及窒息诱导的电活动模式变化表明，电活动起源于肌源性。神经支配在这种活动的控制中起作用，并且对于功能极化至关重要。
