Embriology Flashcards
Week 1 se Forman dos tipos de layrs cuáles son
Embryoblas and Trophoblast
Cuál de las dos capas forman la placenta
Trophoblast
Que significa fertilization, zygote, morula and blastula
F sperm and egg unite in fallopian tube
Z initial diploid cell, and for that the egg has to realese from the Ovary
M ball of cells results of cleavage
B ball of cells when develops Called blastocyst and this itself implant into the uterine wall
En la week 2 que pasa
Se forma 2 layrs and the inner cells becomes bilaminir disc
Cuál es el nombre de los 3 germs layers que forma el epiblast
Endodermo mesodermo y ectodermo
Que pasa con los órganos en la semana 3
Are being stablysed
Cuál es la cavidad que permite conectar el umbilical cord
Chorionic Cavity that is surrounding the egg and connect stalk umbilical cord
En la semana 3 el embrión es más sucemtible a
Malformaciones causadas por la genética o del tipo environmental alcohol and retinoids
En la semana tres se considera egg o embryoblast
Embryo como tal y ya tiene las 3 layers
Que significa gástrulation
Transition from single sheets of cells to 3 distinct layers endoderm epidermis nervous systems, theeth, facial skeleton
Surface ectoderm forms enamel
Que realiza en la semana 3 el neural crest
Forms the rest of tooth
Que forma el mesoderm y el endoderm
M body skeleton all muscles y connective tissue
E hollow organ systems
El empyblast contribuí a q
A formar all three germ layers
Que significa neurulation
Flat neural plate rolls into neural tube
Proceso de de neurulation
El proceso inicia en la cranial side on the dorsal surface
Notochord
Little tuve derived from the mesoderm
Middle of the neural plate
Signal to start folding and this process
Notochord becomes the vertebral column
As the neural tube closes
The aortic arch vessels and corresponding pharyngeal arches and somites
Rolls into a neural tube
Neural plate
Neural fold
Neural groove
Neural tube
Neural crest
Que son los somites
Segments by which the rest of the body develops
