Document Summary
Neural groove: one of the rst indicators of the developing ns; on the posterior aspect of. Neural groove deepens and the neural folds at the lateral margins of the neural plate the tri-laminar embryo become obvious as they elevate and eventually join along the posterior midline to form the neural tube. Neural tube closes at the anterior and posterior neuropores last. Three layers of the neural tube appear in rapid succession: ventricular, marginal, and. Marginal zone appears after ventricular zone; consists of the processes of cells whose cell bodies are located in the ventricular zone; will also be invaded by axons of neurons in the intermediate zone. Intermediate zone is the last to appear; contains immature postmitotic neurons from. Alar plate develops into the posterior horn, basal plate develops into the anterior horn. Alar (posterior) and basal (anterior) plate consist of the ventricular zone and adjacent.
