[Vascularization of the tela choroidea of the prosencephalon of the sheep (Ovis aries)].

The tela choroidea of the prosencephalon in sheep is vascularized by an anterior choroidal artery arising from the rostral branch of the carotid cerebral artery and by a posterior choroidal artery, arising from the caudal cerebral artery, branch of the carotidobasilar system. These two choroidal arteries give off choroidal branches which nourish the capillary networks of the tela. The latter consist of a velar capillary network and of a choroidal capillary network. Together, they drain into choroidal veinules and veins which are tributary of the superficial and of the deep venous systems of the brain.

[Systematization of the angioarchitectonics of the colon in adult man].

The systematization of the angioarchitecture of the human colon was studied in 25 colons, the vascular system of which was injected with gelatinous indian ink. The arterial vascularization of the colonic wall is organized in two morphologically very different types of networks. The first type forms the distributional networks which consist of the subserosal, intermuscular and submucosal networks distributing harmoniously the blood running from the straight arteries. The second type forms the functional networks which consist of the muscular and mucosal networks related to the supply of the essential structure of the colonic wall. These consist essentially of pre- and postcapillary vessels. The venous vascularization of the colonic wall is organized according to a similar pattern. It also consists of three venous networks: the submucosal, intermuscular and subserosal networks which are tributaries of the straight veins and which receive the mucosal and muscular veins.

[Dimensions of the human scapula].

The study of human scapula dimensions is carried out on 110 scapulas of european adults. The statistical analysis of the results concerning the maximum height of the scapula, as well as those of the supraspinous and infraspinous fossa, and also the medial angle, show the absence of statistically significant difference between right and left sides.

[Vascularization of the tela choroidea of the prosencephalon in the cat (Felis domestica)].

The tela choroidea of the prosencephalon in cat is vascularized by an anterior choroidal artery arising from the carotid system and by a posterior choroidal artery arising from the vertebral basilar system. The first essentially supplies the tela and the choroid plexus of the lateral ventricle. The second above all supplies the tela choroidea of the third ventricle. Both, the anterior and posterior choroidal arteries anastomose with their terminal branches. The choroidal branches which arise from these arteries nourish the capillary networks of the tela. These vessels drain into venules and veins which are tributary of the venous circle of the base and of the internal cerebral veins.

[Vascularization of the tela choroidea of the 3rd ventricle in man].

The human choroïd tela of the third ventricle is essentially vascularized by the medial posterior choroïdal arteries, which are collatered branches of the posterior cerebral arteries. In some cases, the tela is also supplied by superior posterior choroïdal arteries which are branches of the pericallosal artery. These different arteries give off short and long choroïdal branches which supply the velate and choroïd capillary networks. The latter drain into the two internal cerebral veins by short and long choroïdal veins.

[The vascular networks of the muscular layers of the human colon].

The vascular networks of the muscular layer of the human colon were studied in 25 cases by injecting the vascular system with gelatinous indian ink. The arterial vascularization of the muscular layer is essentially tributary of the submucosal network through short, medium and long muscular recurrent arteries and accessorily through short and long muscular arteries. These arteries anastomose to form an intermuscular plexus which is also nourished by intermuscular arteries directly arisen from the straight arteries. The venous drainage of the muscular layer is also tributary of the subserous, submucosal and intermuscular networks. This drainage is either of deep type when directed towards the submucosal network, or of mixed type when tributary of both, the subserous and submucosal network.

[Vascularization of the sub-mucosal and mucosal layers of the colon in man].

The vascularization of the submucosal and mucosal layers of the human colon has been studied in 25 cases whose vascular system was injected with gelatinous indian ink. The submucosal layer presents a true vascular crossroads for the arterial and venous anastomotic networks, which are tributaries of the straight vessels. The morphology of these vascular networks is exactly similar. The straight arteries and veins form vascular rings all along the colon, and they anastomose by means of longitudinal and transverse vessels. Many vessels of the muscular and all those of the mucosal layer are tributaries of these vascular networks. The vessels of the mucosal layer include the precapillary arteries, capillary network of the intestinal glands and postcapillary veins. The latter joint and form the mucosal venous trunks, which, in turn, form the mucosal veins, which flow into the submucosal venous network.

[Vascularization of the choroid tela of the 4th ventricle in sheep (Ovis aries)].

The tela choroïdea of the fourth ventricle of the sheep is vascularized principally by the caudal cerebellar artery and the dorsal network of the medulla. The choroidal branches arising from these arteries supply the capillary network of the choroïd plexus. The latter drains towards the sigmoid sinus either through the dorsal veins of the medulla or by an anastomose with the ventral veins. The latter are arched and seem to be metameric. Some choroid veins are tributary of the hemispheric cerebellar veins.

[The vascular networks of the subserous layer of the human colon].

The subserous layer of the colon has, like the small intestine, a rich vascular network. The subserous arteries arise from the straight arteries and are directed towards the taeniae, the surface and free margin of the colon. They terminate at various levels and, by their collateral and terminal branches, form an anastomotic network of vessels whose morphology varies at the level of surface, taenia and the free margin of the colon. From this subserous arterial network arise branches destined to vascularise the muscularis, the fat of the colon and the greater omentum. The subserous venous network copies closely the morphology of the arterial network and is connected by large perforating veins to the submucous venous network.

[Vascularization of the submucosal and mucosal membranes of the 1st and 2d portions of the duodenum in the adult].

The vascularization of the mucosal and submucosal layers of the first and second duodenal segments of adult man is studied in 12 duodenums, in which the vascular system has been injected with gelatinous india ink. The submucosal layer of the duodenum constitutes a true vascular crossroad of two anastomotic networks, one arterial, the other venous, which morphology is completely superimposable. It differs from the jejunum and the ileum because the existence of the Brünner's glands in the submucosa which are vascularized by an important and characteristic capillary network. The arteries of the mucosa are tributary of the submucosal network. They leave precapillary arterioles which reach the Lieberkühn's glands, the Brünner's gland of the mucosa and the duodenal villi. There, they give rise in three capillary networks which are anastomosed at the base of the villi and within the lamina propria. The venous drainage of the mucosa flows into the submucosal venous network.

[Superficial veins of the human spinal cord. An attempt at classification].

By studying the systematization of superficial veins in 70 human spinal cords, it is possible to recognize three different systems: anterior, posterior and lateral. The anterior spinal venous system is formed by an antero-medial trunk extending from the filum terminale to the medulla oblongata, and by two antero-lateral spinal trunks placed in the cranial part of the spinal cord. The posterior, spinal venous system is formed by a postero-medial spinal trunk, extending from the sacral spinal cord to the medulla oblongata, and by two postero-lateral venous trunks, in the thoracic region. The lateral spinal venous system forms an anastomotic system between the anterior and posterior venous systems; it is especially well developed in the lumbar enlargement. In this venous disposition, it can be recognized three types of networks: transversal, longitudinal and arciform, more or less intertwined according to the considered spinal levels.

[The vascular patterns in choroïd tela of the fourth ventricle in dog (Canis familiaris) (author's transl)].

The tela choroïdea of the fourth ventricle of the dog is vascularized principally by the principal and accessory caudal cerebellar arteries but also by the middle cerebellar arteries and dorsal network of the medulla oblongata. The choroïdal branches arising from these arteries supply the capillary network of the choroïd plexus. The latter drains towards the sigmoïd sinus, either directly or through the dorsal plexus of the medulla oblongata. The choroïd plexus drains also partially towards the cerebellar veins and the ventral petrosal sinuses.

[The vascular patterns in choroid tela of the fourth ventricle in cat (Felis domestica) (author's transl)].

The tela choroidea of the fourth ventricle of the cat is vascularized principally by the caudal cerebellar artery and secondarily by the dorsal plexus of the medulla oblongata. The choroidal branches that result from these two systems give the capillary network of the choroidal plexus. This drains rostrally into the emissary veins, tributaries of the cerebellar veins, or caudally, towards the dorsal plexus of the medulla oblongata, which is itself a tributary of the rostral petrosal veins.

[Systematization of the articular surfaces of the carpometacarpal joints (author's transl)].

A study, done on 100 hands, of the systematization of the articular surfaces of the carpometacarpal joints, clearly delineates the variability of circumference, dimesions, and relief of the articular facets. An attempt to draw general conclusions from this morphological study, in terms of arthrokinetics, leads to an understanding of the nature of the joints and the movements that are performed at this site.

[The vascular patterns in choroïd tela of the fourth ventricle in man (author's transl)].

The human inferior choroid tela is vascularized by the posterior inferior cerebellar arteries and the anterior inferior cerebellar arteries. These arteries give off small choroid branches which supply the velate and choroid capillary networks. The latter drain downwards, into the posterior bulbar veins system, or upwards, into the veins of the lateral recess of the fourth ventricle, all of which are tributary to the two superior petrosal veins.
