Published	09/23/2024	{{c1::Oocyte transport}} is when the oocyte is swept into the {{c2::fallopian tube}} by {{c3::fimbriae}}
Published	09/23/2024	Sperm must penetrate the outer layers of {{c1::corna radiata}} and {{c2::zona pellucida}}
Published	09/23/2024	The {{c1::zona pellucida}} is a thick layer of {{c2::glycoproteins}} surronding the oocyte
Published	09/23/2024	A {{c1::zygote}} has {{c2::46}} chromosomes

Published	09/23/2024	{{c1::Cleavage}} is when a zygote undergoes a series mitotic divisions, increasing the number of cells creating a {{c2::blostomere}}
Published	09/23/2024	{{c1::Compaction}} is when the balstomres join together after about {{c2::3}} cleavages / {{c3::2}} days
Published	09/23/2024	A {{c1::morula}} is at least {{c2::16}} blastomeres
Published	09/23/2024	The morula has both an {{c1::inner}} and {{c1::outer cell}} mass
Published	09/23/2024	The {{c1::outer}} cell mass of a morula forms the {{c2::trophoblast}} which later contributes to the {{c2::placenta}}
Published	09/23/2024	The {{c1::inner}} cell mass of a morula becomes the {{c2::embryo proper}}
Published	09/23/2024	A {{c1::blastocyst}} follows the formation of the {{c2::morula}} and conatains an {{c3::empty cavity}}

Published	09/23/2024	The {{c1::embryoblast pole}} is what begins to penetrate between the epithelial cells of the {{c2::uterine mucosa}}
Published	09/23/2024	{{c1::Early spontaneous}} abortion rate is about {{c2::50}}%
Published	09/23/2024	{{c1::Ectopic pregnancy}} is when implantation happens at any location outside of the {{c2::endometrial cavity}}
Published	09/23/2024	{{c1::10%}} of pregnancy related mortality is due to {{c2::ectopic pregnancies}}
Published	09/23/2024	{{c1::Embryoblast}} reorganize into a {{c2::bilaminar disc}} at day {{c3::8}}

Published	09/23/2024	{{c1::Epiblast cells}} will form the {{c2::embryo}}
Published	09/23/2024	{{c1::Gastrulation}} is the change from a {{c2::bilaminar disc}} to a {{c2::trilaminar disc}}
Published	09/23/2024	{{c1::Gastrulation}} begins with a {{c2::primitive streak}} from the {{c3::caudal}} end
