Document Summary
Acb lecture 3 development of the brain and spinal cord. Neural fold: brain is a rounded structure, didn"t start that way neural tube that"s developing, rostral and caudal (or head and tail) Serious problem at time of birth: can be blind, deaf, or unconscious depending on the severity, they have a rudimentary brain stem which may be sufficient to support life but cognitive processing is lost. Summary (development of the neural tube) n the neural plate forms from the ectoderm. The neural crest is on either side of the neural plate. Spina bifida is failure of the caudal neural tube to close. In developing neural tube there is a fair amount of white matter being developed bc neurons from alar plate and basal plate are forming axons as they mature into neurons and these. Marginal zone (axonal processes) e l t n a. Floor plate: another way of showing it, developing neural tube, marginal zone.
