L’image de la semaine 18-2018 r\u00e9sulte de l’observation d’une coupe histologique \u00e0 l’objectif x40 du microscope photonique.<\/p>\n

Elle comporte une structure fibreuse oblongue, d\u00e9limit\u00e9e par une fine tunique autour de laquelle sont dispos\u00e9s des massifs uniform\u00e9ment color\u00e9s et des unit\u00e9s fibreuses.<\/p>\n

  <\/p>\n

La structure oblongue est principalement constitu\u00e9e de fibres, mais de petites unit\u00e9s circulaires et h\u00e9t\u00e9rog\u00e8nes y sont dispers\u00e9es.
\nLes premi\u00e8res correspondent \u00e0 de fins prolongements cellulaires et les secondes \u00e0 des noyaux entour\u00e9s de cytoplasme.<\/p>\n

Cette organisation est caract\u00e9ristique des certains organes nerveux. En l’occurrence, il s’agit d’une coupe longitudinale de nerf, form\u00e9 de fibres nerveuses, prolongements du corps cellulaire des neurones, et de cellules d’accompagnement, pouvant \u00eatre qualifi\u00e9es de gliales.<\/p>\n

L’ensemble est d\u00e9limit\u00e9 par une fine tunique fibreuse. Il s’agit d’une enveloppe de tissu conjonctif fibreux<\/a>, dans laquelle courent des vaisseaux sanguins et dont la paroi est reli\u00e9e \u00e0 des fibres musculaires.<\/p>\n

  <\/p>\n

L’absence de cellules dans la lumi\u00e8re des vaisseaux sanguins, ainsi que le vaste espace liquidien entourant les organes, laissent \u00e0 penser que la coupe a \u00e9t\u00e9 confectionn\u00e9e dans un organisme non Vert\u00e9br\u00e9s \u00e0 vaste cavit\u00e9 corpopelle.
\nEn l’occurrence, il s’agit d’un Lombric.<\/p>\n

  <\/p>\n

L’organisation du syst\u00e8me nerveux central du Lombric a fait l’objet des articles 15-2018<\/a>, 16-2018<\/a> et 17-2018<\/a> de Codex virtualis, avec la description des centres nerveux dorsaux ant\u00e9rieurs, constituant les ganglions c\u00e9r\u00e9bro\u00efdes.<\/p>\n
