The nail is an avascular horny structure, partially covered with the nail fold. It is lying on a nail bed which prolonges forwards with the hyponychium. Each part of the nail apparatus (nail fold, matricial and unmatricial parts of the nail bed, hyponychium) presents a characteristic network which is tributary of dorsal collaterals arising from the digital palmar vessels and from their arcades. These networks are papillar, pseudopapillar, reticular and subdermical. The morphology and density of these networks vary according to their localisation and are superimposed with the histological variations of the different parts of the nail apparatus.

The venous vascularization of the nucleus lentiformis is drained towards the deep venous system of the brain by two ways, one ascending, the other descending. The first one is formed by superior lenticular veins which drain into the thalamo-striate vein, principal tributary of the internal cerebral vein. The second one is formed by inferior lenticular veins which depend from the deep middle cerebral vein, another tributary of the internal cerebral vein. The veins of the nucleus lentiformis, especially the veins of the putamen, present many similarities with these one of the cerebral cortex. They form the center of venous units surrounded by an arterial ring formed by the branches of ramification of the central arteries. The principal vein of the unit is surrounded by a capillary-free space.

The subcephalic fold was handly severed from the embryos and cultivated in liquid medium for 7 days. Because of the embryo age, no heart anlage was observed at the moment of dissection. After 4 hours of culture the cells began to migrate from the explants. After 20 hours a very extended migration ring was observed in all of the cultures; in the explants, one or more newformed tubular or spherical masses of cells throbbed rhythmically. Their size and shape were related to the embryos age: from presomitic embryos, irregular clusters appeared, while starting from two somites embryos tubular, vascular-like structures were formed. The cells of the throbbing areas at submicroscopic observation showed organizing myofibrillar apparatus into the cytoplasm; junctional complexes between the cells and gap junctions in course of organization were present in the vascular-like structures. This suggests that very early, in the lateral mesoderm are the presumptive cardiac cells which can develop \"in vitro\" as myocardic elements even in absence of the interactions that occur during the development \"in vitro\"; the observed vascular-like structures may be considered as an attempt to form a sort of cardiac primordium \"in vitro\", and a further step in the expression of the cardiogenic potentiality, involving cell-cell communications. The serial sections of the embryos enhanced that into the cultivated areas, vessels from yolk sac are always present; this suggests that the vascular structures, i.e. the endothelium may be involved in the determination of the myocardic elements.</p>","PeriodicalId":75534,"journal":{"name":"Archives d'anatomie, d'histologie et d'embryologie normales et experimentales","volume":"75 ","pages":"87-99"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19847064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
