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.
