Script: Към 8-та седмица, ембрионът е физически много по-активен.

Движенията му могат да бъдат бавни или резки, еднократни или повтарящи се, спонтанни или рефлексни.

Учестяват се движенията с главата, врата и докосване на лицето с ръце.

All ages referenced to fertilization, not last menstrual period.
