Electrical and mechanical activities recorded from smooth muscle cells of the human fallopian tube

The membrane activity recorded from the circular muscle layer of the human Fallopian tube showed a unique pattern (slow potential changes), yet the hormonal and adrenergic influences appeared to be much the same as observed in he myometrium. Differences in electrical and mechanical activities, and also the sensitivity to catecholamines during the secretory or proliferative period were elucidated.
