noun

, Embryology.

a tube formed by the closure of ectodermal tissue in the early vertebrate embryo that later develops into the brain, spinal cord, nerves, and ganglia.

neural tube

the structure in mammalian embryos that develops into the brain and spinal cord. Incomplete development results in neural-tube defects , such as spina bifida, in a newborn baby

neural tube

A tubular structure that results from the folding of tissue along the back of vertebrate embryos and develops into the brain and spinal cord. Improper folding of the neural tube is the cause of spina bifida and other birth defects.

First recorded in 1885–90

This is the excised neural tube of my clone, stuck in a vat trying to grow into a brain.

They bulge out of the neural tube, the embryonic primordium of the nervous system.

Later still they become applied closely to the sides of the neural tube and send fibres to it below as well as above.

Immediately beneath the neural tube is situated the notochord (ch).

In their mode of attachment to the neural tube an important change has, however, already commenced to be visible.

The enlarged part of the neural tube, forming the hind-brain, is shewn at (hb).

At its posterior extremity it is primitively continuous with the neural tube (fig. 420), as was first shewn by Kowalevsky.
