title: [Motor reactions and cardiac activity of the fetus at the end of full-term pregnancy and during labor].
abstract: There are two forms of motor activity of the skeletal muscles at the last stages of internatal ontogenesis, i. e. jerky (jMA) and prolonged (PMA). Vagal regulation of the cardiac activity of the fetus associated with development of temporary hypoxemia took place before and after the JMA and the PMA. JMA and PMA occurred during labour pains when the circulation in the uterus decreased and development of JMA and PMA resulted in the compensation of temporary fetal hypoxemia.
