Between these folds is a shallow median groove, the neural groove (Figs. 16, 17). (theodora.com)
The groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into a closed tube, the neural tube or canal (Fig. 18), the ectodermal wall of which forms the rudiment of the nervous system. (theodora.com)
Between the ridges is a neural groove which deepens as the fold become elevated. (lecturio.com)
When the folds meet at midline, the groove becomes a closed tube, the neural tube. (lecturio.com)
A midsagittal groove appears as a result of invagination of the ectoderm centrally and simultaneous elevation of ectodermal tissue alongside the groove to form the neural folds. (medscape.com)
The anterior end of the primitive groove deepens, until it forms a perforation which passes, through the anterior end of the streak and the subjacent entoderm, into the cavity of the entodermal vesicle. (co.ma)
As this perforation passes from the floor of the posterior part of the neural groove into that part of the entodermal vesicle.which afterwards becomes the primitive enteron or alimentary canal, it is called the neurenteric canal. (co.ma)
Ectoderm5
In front of the primitive streak two longitudinal ridges, caused by a folding up of the ectoderm, make their appearance, one on either side of the middle line (Fig. 16). (theodora.com)
The embryo begins as a two-dimensional planar structure, and just prior to the third week, the stage is set for the development of the central nervous system in the area of ectoderm thickening known as the neural plate. (medscape.com)
formed by the longi- nal folding of a thickened Chorion ite of ectoderm, the neural plate, which is the rudiment of the whole of the central and peripheral portions of the nervous system, except per- haps the olfactory nerves, and the end organs of the sensory nerves. (co.ma)

Now a new discovery led by Brown University scientists deepens the basic understanding of how the genetic mutation that causes SMA appears to undermine the communication between motor neurons and the muscles they control. (regenerativemedicine.net)
Last year her lab published evidence that one mechanistic consequence of the disease is a disruption of the process by which neurons can recycle and reuse proteins needed for neural control of muscle. (regenerativemedicine.net)
Primitive streak1
After the coalescence of the neural folds over the anterior end of the primitive streak, the blastopore no longer opens on the surface but into the closed canal of the neural tube, and thus a transitory communication, the neurenteric canal, is established between the neural tube and the primitive digestive tube.

Uterine tube3
After the sperm enters the oval cytoplasm in the uterine tube, the maternal and paternal chromosomes combine to form a zygote, completing fertilization. (medscape.com)
The ciliary action of the uterine tube transports the zygote to the uterus, during which it undergoes a series of mitotic divisions and transforms into the ball of small cells termed blastomeres. (medscape.com)
Fertilisation is the term applied to the union to form a zygote which contains the typical nur The meeting of the gametes and their union or middle part of the uterine tube. (co.ma)
