Summary Introduction
To review:
Match the term expulsion stage with the most closely related description given below:
Begins with the onset of the true labor
Begins as the dilation of the cervix is complete
Birth
Described by quick fetal growth
Incision via the peroneal musculature
A sheet of follicular cells around the oocyte
An enzyme in the acrosome
The cytoplasm of the oocyte
Time of embryonic/early fetal development
Described by the continued development of the organ systems
Introduction:
Labor is commonly known as childbirth. It is the process in which the fully grown fetus moves out of the woman’s body through the cervix. It occurs in three stages namely dilation, active labor, and expulsion stage.
