title: [Cervical muscular tissue in pregnant women and Macaca monkey females. Functional evaluation "in vivo" using an electrophysiological technique].
abstract: In vivo recordings of electrophysiological activity of the muscular tissue in the cervix, in both the pregnant human female and Macaca monkey, showed that most of the cervix did not present a measureable electrical activity. Only muscular tissue located in the peripheral, supra vaginal portion of the cervix, exhibited a noticeable propagated E.M.G. activity, which always originated in the fundus. This accords well with histological studies which demonstrate that this portion of the cervix is the richest in muscular tissue. It is however possible that the other muscular cells of the cervix have a role other than a contractile one, and may be responsible for synthetizing or catabolizing constituant parts of the cervical connective tissue.
