holospondyle

CONT: Nous rappellerons que les vertèbres des téléostéens sont holospondyles, monospondyles et amphicoeliques, c'est-à-dire entièrement soudées et osseuses, avec un seul centre par segment et biconcaves.

OBS: The extent of ossification around the notochord, the presence or absence of a notochordal canal, the presence of absence of cartilaginous arch remnants in the centrum, the fusion or non-fusion of the arches with the centrum, and the nature of the zygapophyses should have at least broad evolutionary significance [in teleosts].
OBS: The neural and haemal arches may be partly ossified, and the spines may or may not be fused with the arches.
OBS: [said] of groups of atoms or cellular structures joined or coalesced.
