Final answer:
During the latent phase of the first stage of labor, the cervix undergoes gradual dilation and effacement. On average, the cervix dilates around 1 centimeter per hour.
Step-by-step explanation:
In the latent phase of the first stage of labor, the cervix undergoes gradual dilation and effacement, or thinning. This phase is characterized by slow and irregular contractions, which gradually become more frequent and intense as labor progresses. The rate of change in the cervix during this phase varies from woman to woman, but on average, the cervix dilates around 1 centimeter per hour. It's important to note that this rate can vary and is influenced by factors such as the mother's previous childbirth experience and individual differences.
