CHE SIGNIFICA DEUTEROSTOME IN INGLESE
deuterostomi
Deuterostomi sono un superfilo di animali. Sono un subtaxon del ramo della Bilateria del subregno Eumetazoa, e si oppongono ai protostomi. Deuterostomi sono distinti per lo sviluppo embrionale; In deuterostomi, la prima apertura diventa l'ano, mentre in protostomi diventa la bocca. Deuterostomi sono anche noti come Enterocoelomates perché il loro coelombo si sviluppa attraverso enterocoamente. Ci sono quattro fili esistenti di deuterostomi: ▪ Phylum Chordata ▪ Phylum Echinodermata ▪ Phylum Hemichordata ▪ Phylum Xenoturbellida Superphylum La Deuterostomia è stata ridefinita nel 1995 sulla base di analisi delle sequenze molecolari quando i lophophorates sono stati rimossi e combinati con altri animali protostomici per formare il superfilo Lophotrochozoa. Anche il phylum Chaetognatha può appartenere. I gruppi estinti possono includere il phylum Vetulicolia. Echinodermata, Hemichordata e Xenoturbellida formano la cladi Ambulacraria. Il presente phylum Priapulida ha anche uno sviluppo deuterostomico, nonostante sia altrimenti posto all'interno dei protostomi. In entrambi i deuterostomi e protostomi, uno zigoto si sviluppa per la prima volta in una sfera cava di cellule, chiamata blastula.
definizione di deuterostome nel dizionario inglese
La definizione di deuterostomo nel dizionario è qualsiasi membro del gruppo principale di animali definito dal fatto che durante il primo sviluppo embrionale la prima apertura a formare diventa l'ano dell'animale. L'opposto è il protostoma.
