Document Summary
Chapter 9 psyc2410: 3 weeks after conception tissue to develop into ns is a neural plate: a small patch of ectodermal tissue on the dorsal surface of the developing embryo. They still have the potential to develop into most types of mature ns cells, but not other types. Migration: once created in the ventricular zone of the neural tube, cell migrate to their target locations. Radial migration: from ventricular zone outward in a straight line toward the outer wall of the tube. Tangential migration: occurs at a right angel to radial migration parallel to tube"s walls. Somal translocation: an extension grows from the developing cell in the general direction of the migration; the extension seems to explore the immediate environment for attractive and repulsive cues as it grows. Then, the cell body itself moves into and along the extending process, and trailing processes are retracted.
