• This paper addresses a fundamental question in developmental biology, that is, how morphogenetic movements driving tissue folding are patterned to occur with the correct spatiotemporal dynamics. (elifesciences.org)
  • 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)
  • The middle germ layer of an embryo derived from three paired mesenchymal aggregates along the neural tube. (lookformedical.com)
  • In the placodes of the forming tubes of the salivary glands in the Drosophila embryo, we previously identified spatially defined cell behaviors of cell wedging, tilting, and cell intercalation that are key to the initial stages of tube formation. (elifesciences.org)
  • 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)
  • Here, we address what the requirements are that ensure the continuous formation of a narrow symmetrical tube from an initially asymmetrical primordium whilst overall tissue geometry is constantly changing. (elifesciences.org)
  • The pudendal nerve, derived from S2, S3 and S4, leaves the pelvis m edial to the sciatic nerve via the higher sciatic foram en. (dnahelix.com)
  • In these families, we observed that neural tube defects and birth defects overall occurred at a higher rate in the maternal lineage compared with the paternal lineage. (cdc.gov)
  • Finally, we will study which features of temporally complex odours are used for navigation behaviour by simultaneously recording and correlating the animal's respiration sampling strategy, the dynamic odour profile encountered by the animal and neural activity from early and higher order olfactory areas in freely moving mice.

  • 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)
  • The reactor tube inserts have a small black dot on one end only. (mylifeforceenergy.com)
