true
The cervix typically dilates to about 10 cm during the dilation stage of labor
true
The cyclic changes that occur monthly in the ovary constitute the ovarian cycle.
true
The diamond-shaped region of a female's external genitalia found between the anterior end of the labial folds, the anus posteriorly, and the ischial tuberosities is called the perineum.
