Neural plate

In embryology, the neural plate is a key developmental structure that serves as the basis for the nervous system. There are four stages of neural plate and neural tube formation: formation, bending, convergence, and closure. Cells take on a columnar appearance in the process as they continue to lengthen and narrow. The ends of the neural. plate, known as the neural folds, push the ends of. the plate up and together, folding into the neural tube, a. structure critical to brain and spinal cord development. This process as a whole is termed primary neurulation. It was seen in an experiment that did not correctly develop the. neural plate, so regions and regions of the tube did not decrease in height and. decrease in shape in the same way as MHP. These change in shape are referred to as dorsal-lateral hinge points (DLHP) These change the shape and height and become wedge-shaped in shape. These changes are known as medial hinge point (MHP) because of their involvement with this area of the midline. They are not derived from the anterior to the primitive knot.
