Blink-Startle Response

From The Biology of Prenatal Development.Buy Now

Script: Rive sou 24 semèn, pòpyè yo ouvri ankò e sa fè fetis la bat je l tankou yon moun ki sote. Se konsa fetis la reyaji lè l tande yon bri ki fò e ki siprann li. An jeneral, reyakyon sa a fèt pi bonè nan fètis la si se yon tifi.

Anpil chèche di si fetis la tande gwo bri, sante l ap peye sa.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
