Deuterostômios ( português brasileiro) ou deuterostómios ( português europeu) ( deuterostomia Grobben, 1908; do grego deuteros, posterior + stoma, boca), é um grupo de animais ligados por diversos aspectos embrionários peculiares, como a forma de clivagem, a forma de suas larvas, o desenvolvimento do celoma e pelas aberturas embrionárias ...

'mouth second') are bilaterian animals of the superphylum Deuterostomia ( / ˌdjuːtərəˈstoʊmi.ə / ), [3] [4] typically characterized by their anus forming before the mouth during embryonic development.

Deuterostomia. Deuteróstomos. Los deuterostomados o deuteróstomos ( Deuterostomia, del griego «δεύτερος» segunda y «στόμα» boca, i.e. "boca segunda"), significando que en las etapas iniciales del desarrollo embrionario se forma primero el ano y la boca en segundo lugar, en contraposición a los protóstomos, en los ...
The embryological origin of the mouth and anus is an important characteristic, and forms the morphological basis for separating bilaterian animals into two natural groupings: the protostomes and deuterostomes .
In cell biology, a deuterosome is a protein structure within a multiciliated cell (such as an epithelial cell of respiratory tract) that produces multiple centrioles . Most cells in human body possess one primary cilium, [1] a relatively small protrusion of the cell membrane that looks like a stick or a finger under the electron ...
