Abstract

Spontaneous electrical activity of myometrium was studied in areas of the uterus body, zone of its connection with uterine tube, and cervix at intravenous administration of various acetylcholine concentrations. Under these conditions, changes of the frequency and amplitude characteristics of rhythmogenesis were studied both separately and in their combined active state. The presence of 10−3 M acetylcholine in the animal blood creates the most optimal conditions for synchronization and coordination of activities of all studied uterus areas.
