How To Use somite In A Sentence
- The basis for the confusion arises from the visible suture between somites 4 and 5, which suggests that the fusion is not complete.
- Eye development in zebrafish first becomes morphologically obvious at the 6 somite stage, the time at which the optic lobes evaginate from the diencephalon.
- The simplest two-instrument cell injection technique for both primitive streak stage and for early somite stage embryos will be described.
- In lancelets, the trunk somites extend and fuse ventrally to give the unsegmented periviscelar coelom.
- Somites differentiate into particular axial structures depending on their position along the antero-posterior axis.
- The neural tube of the body tends to segment in an orderly way along the boundaries between somites.
- For instance, somites, one of the body elements characteristic of the phylotypic stage, form under the influence of a somitic clock, rhythmic waves of molecular activity that sweep the length of the trunk and tail. The Politically Incorrect Guide to Darwinism and Intelligent Design Review: Simply Incorrect Embryology (Chapter 3) - The Panda's Thumb
- He was led to enunciate the following theses: -- [450] (1) that the mouth and anus of Vermes, Mollusca, Arthopoda, and probably Vertebrata, is derived from the elongated mouth of an ancestor resembling the Actinozoa; (2) that somites are derived from a series of archenteric pouches, like those of Actinozoa and Medusæ; (3) that excretory organs (nephridia, segmental organs) are derived from parts of these pouches which in the ancestral form, as in many polyps, were connected by a circular or longitudinal canal, and opened to the exterior by pores.
