Hormonal Stress Response


4 months, 1 week

From The Biology of Prenatal Development.Buy Now

Script: 4 MAANDE

As 'n naald teen 16 weke in die fetus se maag gesteek sou word, sal dit 'n hormonale stresrespons veroorsaak. Nor-adrenalien, of nor-epinefrien, word dan in die bloedstroom vrygestel.

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