Summary
The isolated non‐pregnant cervix has been shown to exhibit spontaneous isotonic and isometric contractility and to respond to drugs. PGE2 causes a marked relaxation whilst the effect of PGF2α is more variable. Oxytocin and adrenaline cause contraction of the muscle.
The implications of the finding that the cervix can show isotonic and isometric contractility and the effects of prostaglandins are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
