The amnion is a crucial component of embryonic development in mammals, including humans. This thin, protective membrane surrounds and encloses the growing fetus within the amniotic cavity, filled with amniotic fluid. This clear liquid provides a cushioning and protective environment for the developing embryo or fetus, regulating temperature, protecting against physical injury, and preventing infections. The amnion also allows for fetal movement and helps maintain a stable environment for the developing fetus. During labor, the amnion ruptures, commonly known as the “water breaking,” which signals the onset of childbirth. Overall, the amnion is a vital part of fetal development, ensuring the survival and well-being of the growing fetus.
