Sense of Smell


6 months, 2 weeks

From The Biology of Prenatal Development.Buy Now

Script: Semua komponen yang perlu untuk deria bau kini berfungsi. Kajian ke atas bayi tidak cukup bulan mendedahkan ia berupaya mengesan bau seawal 26 minggu selepas persenyawaan.

Jika bahan manis hadir dalam bendalir amnion, kadar fetus menelan meningkat. Sebaliknya, kadar fetus menelan menurun apabila bahan pahit dimasukkan. Ekspresi wajah biasanya akan bertukar selepas ini.

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