At this time, the blastocyst undergoes morphological changes to produce a bilaminar embryonic disc. ]]> 2021-05-24 02:38:50 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552351248 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552354849 2021-05-24 02:40:18 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552354849 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552355024
The blastocyst will develop further while it implants into the uterine wall:
The inner cell mass differentiates into epiblast and hypoblast cells to generate the bilaminar
embryo:
1. The epiblast will form the fetus,
2. The hypoblast is transiently present, and forms Heuser’s (exocoelomic)
membrane that will cover the internal surface of the blastocoel
The trophoblast will differentiate into:
1. Cytotrophoblast: continuous cellular layer that envelops the bilaminar embryo
and blastocoel/primitive yolk sac
2. Syncytiotrophoblast:
• Syncytium around the cytotrophoblast.
• Allows invasion of embryo into the endometrium through production
of proteolytic enzymes that break down the extracellular matrix.
• Produces human chorionic gonadotropin hormone (hCG)]]> 2021-05-24 02:40:22 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552355024 alinacburgess https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552355446 2021-05-24 02:40:33 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552355446 raharjoregina https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552363228 2021-05-24 02:44:02 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552363228 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552368328 2021-05-24 02:46:14 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552368328 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552368443 2021-05-24 02:46:17 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552368443 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552396200 2021-05-24 02:59:25 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1552396200 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1556019080 Lesdothis

This involves the formation of the telencephalic vesicles.
If the SHH gene is abnormal, the signalling for the development of the L/R axis will also be abnormal and the procencephelon will not develop into the 2 telenceophalic vesicles, resulting in holoprocencephaly.]]> 2021-05-25 02:28:15 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1556023478 tjmorsanuto https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1556025136 2021-05-25 02:28:54 UTC https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1556025136 moniksoni06 https://padlet.com/BossAnnemiek/rkw4lvgyejuute1e/wish/1556028103 Occurs in 3 stages: pronephros, mesonephros and metanephros.
of thes stages, the pro and mesonephprons are regressive, with the metanephros forming the functional kidney.

the pronepheros forms 1st at 3 weekss fo gestation, with the mesonephrons, consists of filtering units, forming at the 4th week, caudal to the propherons, a simple tubule.

the proepherons devlopment begins in the cervical region of the embryo, segemted divions of imtermediate mesoderms form tubules known as nephrotones. there are 6 to 10 pairs of these. these tubules, join into the pronephric duct thats all.

the mesonepthrons ventually degenerate into the wolffian duct. from which the uretic bud forms.
