Study Notes
Parturition Phases
- The phase of parturition involving Uterine Quiescence and Cervical Softening is the Progestational Phase.
- The last few hours of human pregnancy are characterized by increased maternal circulating estrogen levels.
- During the Activation Phase of parturition, the uterus becomes responsive to oxytocin and prostaglandins, and uterine contractions increase in frequency and intensity.
Cervical Changes
- The early stage of remodeling of the cervix is termed cervical softening.
- The cervix undergoes ripening and effacement in response to increasing estrogen and progesterone levels, usually around 37-40 weeks of gestation.
