Neural Development Flashcards
Prenatal stages
pre-embyronic day 0-14
embyronic stage
fetal stage
embryonic stage
cell proliferation- division
cell migration- movement
cell differeniation- more specialised cells= 3 layers of cells
embryonic disk
endoderm - gut lining/ pancreas/ respiratory
mesoderm- muscles/ skeleton/ excretory/ circulatory
ectoderm - sensory organs/ hair/ skin/ nails/ whole nervous system
neural tube defects
lack of folate
failure of closure of the neural tube
spina bifida
lower= can’t control bladder/ bowl/ can’t move legs
foetal development
week 13-24
neurogenisis
most neurons
major brain development
week 25-38- brain development
tetragens
substances and conditions that impact embryos
dose/ heating organisims age/ neagtive influences
most sensitive weeks 2-9
