The neural tube of vertebrates develops by
A)folding of ectoderm tissue.
B)migration of mesoderm cells.
C)fusion of ectoderm and mesoderm.
D)extension of endoderm into a thin spinal column.

Question

Quizplus · Accepted Answer

The neural tube of vertebrates develops through the process of folding of the ectoderm tissue. This occurs during the gastrulation stage of development, where the cells of the ectoderm fold inward and form a groove, which eventually seals to form the neural tube. This process is crucial for the development of the nervous system. Migration of mesoderm cells and fusion of ectoderm and mesoderm are not involved in the development of the neural tube. Extension of endoderm into a thin spinal column does not occur in the development of the neural tube.
