Cervical effacement, also known as cervical thinning, refers to the gradual shortening and thinning of the cervix during pregnancy. The term "cervical effacement" is commonly used in medical settings, but there are other terms that can be used to describe this process. Some synonyms for cervical effacement include cervical ripening, cervical softening, and cervical dilation. Essentially, all of these terms describe the process in which the cervix prepares for labor by becoming thinner, softer, and dilated. While the terminology may vary, understanding the different stages of cervical effacement is important for both healthcare providers and expectant mothers.
