So what are neural crest cells? neural crest cells are cells that arise in proximity to the neural tube.
00:08
So what is neural tube? so we have to draw the diagram.
00:12
So when there is an embryo, when an embryo is formed, it forms a tube -like structure to form a triploblastic embryo.
00:24
So triplastic embryo refers to the formation of ectoderm.
00:30
Mesoderm and endoderm.
00:33
So these three formations occur when the cell folds like so.
00:38
So when an embryo folds in this pattern, so there is a formation of neural tube.
00:46
So neural tube is forms the spinal cord and the brain.
00:50
It forms a nervous system structures.
00:53
So the cells or the cells that form next to the neural tube are called as neural cerex cells.
01:02
So these cells form many types of cells from the ectoderm, mesoderm and also the endoderm...
