neurulation
(noun)
The process that forms the vertebrate nervous system in embryos.
(noun)
The process by which the beginnings of the vertebrate nervous system is formed in embryos.
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.
