[Responses to electrical stimulation in the ruminal artery-rumen wall preparation (author's transl)].
The responses of the ruminal artery-rumen wall preparation to the following periartery stimulations: 64-128 HZ, 5-100 ms, 30-50 V, 10-30 s have been studied. The responses to electrical stimulation were biphasic in nature (contraction-relaxation). Six distinct types were classified, related to their differentiating characters. There seems to be important differences between the ruminal smooth muscle and the smooth muscle at another organic levels, since the responses to frequencies higher than 64 HZ in preparations of non-ruminal smooth muscle originated rather relaxing responses.
