During which phase of labor does the cervix typically begin to efface?

In the context of labor, the cervix begins to efface during the latent phase. This phase marks the beginning of labor, where the body prepares for delivery. During the latent phase, the cervix becomes thinner and shorter, a process known as effacement. This phase is crucial because it signifies the gradual opening and thinning of the cervix in anticipation for the subsequent stages of labor.

While the active phase does involve further dilation of the cervix, it is during the latent phase that effacement starts to take place. Understanding the stages of labor and associated changes is vital for EMTs and medical professionals, as this knowledge aids in providing appropriate care and support to laboring individuals.
