neurulation

Examples of neurulation in the following topics:

• Neurulation

  • Following gastrulation, the neurulation process develops the neural tube in the ectoderm, above the notochord of the mesoderm.
  • Neurulation is the formation of the neural tube from the ectoderm of the embryo.
  • Beginning in the future neck region, the neural folds of this groove close to create the neural tube (this form of neurulation is called primary neurulation).
  • Secondary neurulation of vertebrates occurs when primary neurulation terminates.
  • Each organism uses primary and secondary neurulation to varying degrees (except fish, which use only secondary neurulation).

• Embryonic Development

  • The spinal cord derives from the neural tube in two processes: primary and secondary neurulation.
  • Primary neurulation begins after the neural plate has formed.
  • Each organism uses primary and secondary neurulation to varying degrees.
  • Neurulation in fish proceeds only via the secondary form.
  • In avian species the posterior regions of the tube develop using secondary neurulation and the anterior regions develop by primary neurulation.

• Establishing Body Axes during Development

  • The neural tube develops in two ways: primary neurulation and secondary neurulation.
  • Primary neurulation begins after the neural plate forms.
  • Neurulation in fish proceeds only via the secondary form.
  • In avian species the posterior regions of the tube develop using secondary neurulation and the anterior regions develop by primary neurulation.
  • In mammals, secondary neurulation begins around the 35th somite.

• Development of the Peripheral Nervous System

  • The sequence of stages from neural plate to neural tube and neural crest is known as neurulation .
  • During neurulation, the borders of the neural plate, also known as the neural folds, converge at the dorsal midline to form the neural tube.

• Bilaminar Embryonic Disc Development

  • Through the through the process of neurulation, the notochord induces the formation of the notochord in the embryonic disc.

• Embryonic Development of the Brain

  • Neurulation is the formation of the neural tube from the ectoderm of the embryo.
  • Beginning in the future neck region, the neural folds of this groove close to create the neural tube (this form of neurulation is called primary neurulation).

• Development of Nervous Tissue

  • The sequence of stages from neural plate to neural tube and neural crest is known as neurulation.
