A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester -match to term fertilized egg, after nuclear fusion
zygote
A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester -match to term first 2 weeks; zygote, 2-8 cell stages, morula, blastocyst.
B)Pre-embryonic stages
A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester developing organism from 2-8 wks
embryo
A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester developing organism from 9wk-birth
fetus
A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester embryo or fetus + all surrounding membranes derived from zygote
conceptus
A)zygote B)Pre-embryonic stages C)Embryo D)Fetus: E)Conceptus: F)Trimester one third of the human gestational period; not related to developmental stages.
trimester
(migration/induction ) is growth
induction
(induction/migration) differential growth
migration
(epithelial folding/cavitation) is selective cell death
epithelial folding
(epithelial folding/cavitation) is cell differentiation
cavitation
(hyperplasia/hypertrophy) is increase in cell size
hypertrophy
(hyperplasia/hypertrophy) is increase is cell number
hyperplasia
TGF and EGF increase cell (number/size)
number
(induction/differential growth)One side or part of a structure grows faster than another. This is a major mechanism which allows organs to reach their ultimate shape.
differential growth
(induction/differental growth) A chemical signal will cause a change in cells, resulting in migration, differentiation, or other change.
Chemical can be a surface signaling molecule or some chemical released into the extracellular matrix.
It influences the genome to differentiate in any of a number of varied ways.
