Electromyographic evaluation of the spontaneous and drug-induced motility of the cervix in sheep.
Recordings of electrical activity of the cervix were obtained in cycling and ovariectomized ewes that were fitted with extracellular electrodes and strain gauge transducers. Spontaneous electrical and mechanical events occurred with a typical cyclic pattern. Methods of evaluation of drug action on the cervix are suggested with respect to the observed spontaneous cyclic activity of the organ.
