Neurulation refers to the folding process in vertebrate embryos, which includes 
the transformation of the neural plate into the neural tube. The embryo at this 
stage is termed the neurula. The process <b>begins</b> when the notochord induces the 
formation of the central nervous system (CNS) by <b>signaling</b> the ectoderm ... In 
<b>primary neurulation</b>, the neural plate creases inward until the edges come&nbsp;... In the developing chordate (including vertebrates), the neural tube is the 
embryonic precursor ... <b>Primary neurulation</b> divides the ectoderm into three <b>cell</b> 
types: ... <b>Primary neurulation begins</b> after the neural plate forms. ... occurs early in 
development and results from the activity of several <b>secreted signaling</b> molecules
. The neural plate is a key developmental structure that serves as the basis for the 
nervous ... In <b>primary neurulation</b>, the layer of ectoderm divides into three sets of 
<b>cells</b>: the neural ... The formation of the neural plate <b>starts</b> when dorsal mesoderm 
<b>signals</b> ectodermal <b>cells</b> above it to lengthen into columnar neural plate <b>cells</b>. A biochemical cascade, also known as a <b>signaling</b> cascade or <b>signaling</b> pathway
, is a series of ... Each <b>signal</b> transduction occurs with a <b>primary</b> extracellular 
messenger that ... The <b>cellular response</b> in <b>signal</b> transduction cascades involves 
alteration of the ... &quot;Getting <b>Started</b> in Biological Pathway Construction and 
Analysis&quot;. Ectoderm is one of the three primary germ layers in the very early embryo. The 
other two layers are the mesoderm (middle layer) and endoderm (most proximal 
layer), with the ectoderm as the most exterior (or distal) layer. It emerges and 
originates from the outer layer of germ <b>cells</b>. ... During <b>primary neurulation</b>, the
