The lateral fasciculus of the brachial plexus pierced the coracobrachialis muscle, gave muscular branches to the coracobrachialis and biceps brachii, and then divided at the middle of the upper arm in two terminal branches. The first one trifurcated, giving two branches for the brachialis muscle, and the lateral antebrachial cutaneous nerve; the second one corresponded to the lateral root of the median nerve. This lateral root joined the medial root, and gave the proper median nerve. No accurate description of a similar case has been found in the literature.

The main common characteristic between them was the unilateral existence of a superficial brachial artery. The other arterial variations encountered were mostly represented by an assembling of some of the usual branches of the axillary artery in a common trunk which we called thoracdorso-subscapular trunk. In two cases, this trunk gave rise to the posterior circumflex humeral artery. Several nervous anomalies accompanied these atypical vascular patterns. The medial fasciculus of the brachial plexus was absent in one subject and an aberrant course of the brachial artery through the median loop was then observed. The two other cadavers showed variations in the distribution of the intermediate trunk and lateral fasciculus of the plexus. Embryologically, the persistence of various segmental arteries in the axilla seems to be responsible for the described anomalies. Otherwise, the present study indicates that the segmental origin of the axillary artery and its pattern of branching may determine the arrangement of the brachial plexus during the fetal development.</p>","PeriodicalId":75534,"journal":{"name":"Archives d'anatomie, d'histologie et d'embryologie normales et experimentales","volume":"72 ","pages":"57-67"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13633002","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}

So we have an experimental model allowing the influence on the osteogenesis of various factors, local or general, natural or experimental, to be studied. Ossification occurs in this model only in cases of histocompatibility between donor and recipient. It is constant after autotransplantation or isotransplantation. It is never seen after heterotransplantation. In cases of homotransplantation its frequency varies: this is not influenced by the technical conditions of implantation but by tissue compatibility and the age of the animals giving and receiving. A private perichondrium cartilage retains its osteogenic potency. A cartilage killed by alcohol or cold no longer demonstrates its osteoformative capacities, even when put into contact with a living cartilage. Our findings are difficult to reconcile with the hypotheses invoking the osteogenic potency of the periosteum, or the intervention of substances either inducing osteoformation or inhibiting vascular invasion, for the explanation of endochondral ossification. However, they lead one to the opinion that chondrocytes play an active role in its release.</p>","PeriodicalId":75534,"journal":{"name":"Archives d'anatomie, d'histologie et d'embryologie normales et experimentales","volume":"72 ","pages":"81-96"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13665251","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}
