Neurulation vs. Gastrulation: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on March 5, 2024
Neurulation is the process forming the neural tube, precursor to the central nervous system, while gastrulation forms the embryonic germ layers.
Key Differences
Neurulation is a pivotal embryological process where the neural plate transforms into the neural tube, eventually developing into the brain and spinal cord. Gastrulation, in contrast, is an earlier stage where the single-layered blastula reorganizes into a multilayered structure called the gastrula, laying the foundation for complex body structures.
In neurulation, the neural plate's edges rise and fold towards each other, fusing to form the neural tube. This tube is the basis for the central nervous system. Meanwhile, gastrulation involves the movement of cells to establish three primary layers: ectoderm, mesoderm, and endoderm, each giving rise to different organs and tissues.
Neurulation can be further divided into primary and secondary stages, primarily focusing on the development of the brain and spinal cord. On the other hand, gastrulation is integral in establishing the body's basic plan, including symmetry and the rudimentary arrangement of tissues and organs.
During neurulation, defects can lead to serious conditions like spina bifida or anencephaly. In gastrulation, disruptions can result in more widespread developmental issues due to the foundational role of the germ layers in overall organogenesis.
The end of neurulation is marked by the closure of the neural tube, signaling a key transition in the nervous system's development. Conversely, the completion of gastrulation sets the stage for subsequent processes like organ formation, encompassing a broader range of developmental events.
