The 23rd pair is known as the sex chromosomes, and they determine the babies sex]]> 2017-06-03 00:35:28 UTC https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175040646 brown_timothy https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175040888 When the embryo is 2 weeks old, neurulation occurs. This signals the beginning of your central nervous system forming. At around 25 days, your brain begins to form]]> 2017-06-03 00:43:32 UTC https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175040888 brown_timothy https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175041075 Heredity and environment are engaged from the beginning, called coaction. From weeks 3-8, the embryo is in it's embryonic stage, a period of the greatest sensitivity to teratogens]]> 2017-06-03 00:52:02 UTC https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175041075 brown_timothy https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175041412 After the embryonic stage comes the fetal stage, which lasts from 9 weeks till birth. Eyes, teeth, ears, genitalia, and the central nervous system develop. The fetus now has a lesser chance of being effected by teratogens ]]> 2017-06-03 01:05:38 UTC https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175041412 brown_timothy https://padlet.com/brown_timothy/f6lqu8wxah4z/wish/175042057 After birth, the brain's neurons continue to reproduce at a rapid pace. The bones continue their development as well. The visual and auditory cortices experience rapid synaptic growth.
