The notochord is an evolutionary novelty in vertebrates that functions as an important signaling center during development. Notochord ablation in chicken has demonstrated that it is crucial for pancreas development; however, the molecular mechanism has not been fully described. Here, we show that in ...
How did members of the subphylum Urochordata and the phylum Chordata evolve into vertebrates? How do animals of the phylum Porifera differ from animals of the phylum Cnidaria? Do members of the phylum Chordata have a notochord? Why does the rat fall under the phylum Chordata? Why do sala...
the developing central nervous system in vertebrates. The present study addressed the histochemical detection of β-gal-pH6 enzymatic activity in the developing postnatal olfactory epithelium in the mouse. This activity was detected in the intermediate layer of the olfactory epithelium. As development ...
Vertebrates belong to the group of chordates characterized by a dorsal neural tube and an anteroposterior axis, the notochord. They are the only chordates to possess an embryonic and pluripotent structure associated with their neural primordium, the neural crest (NC). The NC is at the origin of...
The thyroid gland of vertebrates had its beginnings in what group of animals? a. Echinoderms b. Deuterostomes c. Invertebrate chordates d. Protostomes Thyroid gland: The thyroid gland is a structure found in chordates. I...
notochord - a flexible rodlike structure that forms the supporting axis of the body in the lowest chordates and lowest vertebrates and in embryos of higher vertebrates chine - backbone of an animal canalis vertebralis, spinal canal, vertebral canal - the canal in successive vertebrae through which...
blastomeres of the early embryo frequently resulted in complete axial duplications highly reminiscent of the Spemann organiser grafting experiment [81,82]. In fact, this ‘axis induction essay’ played a key role in establishing the canonical Wnt signalling pathway in vertebrates in the 1990s [83–...
Intracellular BMP signaling regulation in vertebrates: pathway or network? Dev Biol. 2001;239(1):1–14. 42. de Pater E, Ciampricotti M, Priller F, Veerkamp J, Strate I, Smith K, et al. Bmp signaling exerts opposite effects on cardiac differentiation. Circ Res. 2012;110(4):578–87. ...
In vertebrates, pressure receptors in the skin. The nerve ending is surrounded by multiple concentric layers of connective tissue that provide mechanical resistance to deformation. paclitaxel See taxol. pacsins A family of cytoplasmic adaptor phosphoproteins (protein kinase C and casein kinase substrate...
