Development of the vertebrate central nervous system formation of the neural tube

Abstract. The vertebrate central nervous system develops from a single plate of ectoderm cells that fold into the neural tube. Localized signalling centres are placed at defined positions both outside and within the neural plate and tube, and trigger the differentiationNeural Development Unit, UCL Institute of Child Health, London, UK. The developmental process of neurulation involves a series of coordinated morphological events, which result in conversion of the at neural plate into the neural tube, the primordium of the entire central nervous system (CNS). development of the vertebrate central nervous system formation of the neural tube

Drosophila. The NotchDelta system is also present in vertebrates where it is also important in the development of the embryo. There are at least 4 Notch genes 3 of which are important in the development of the nervous system. It is also present in the Xenopus where it expands the neural plate at the expense of the ectoderm.

During early development of the vertebrate embryo, a longitudinal groove on the neural plate gradually deepens and the ridges on either side of it (the neural folds) become elevated and ultimately meet, transforming the groove into a closed tube, the ectodermal wall of which forms the rudiment of the nervous system.

Neurulation. Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube. The embryo at this stage is termed the neurula. The process begins when the notochord induces the formation of the central nervous system

(D) As development continues, the neural tube adjacent to the somites becomes the rudimentary spinal cord, and the neural crest gives rise to sensory and autonomic ganglia (the major elements of the peripheral nervous system).

The earliest stage in the development of the vertebrate nervous system from the ectoderm. Neural Tube. induced formation of ventral neural tube. Neural Crest. Collections of neurons outside the central nervous system that provide autonomic innervation of body organs.

Introduction. The spinal cord is the central nervous system part that extends into the axial skeleton and provides the twoway traffic required to interact with our environment. During pregnancy, early development of the spinal cord is influenced by the maternal dietary requirement for folate for closure of

the midline to form the neural tube, which will develop into the central nervous system. The neural tube detaches from the skin ectoderm and sinks beneath the surface. At this stage, groupings of ectodermal cells, called neural crests, develop as a column on each side of the neural tube. The.
