Morphology of the main sources of blood supply of the brain of the bovis
In article the vazorentgenografiya technique with use of the modified mix of Kulchitsky K.I. is described. This weight represents a suspension of lead minium in turpentine with alcohol ethyl rectified and glycerin. For research of the vascular course of a brain of a bull house carried out an injection of vessels of the head through the right and left general carotids. To prevent a weight effluence through collateral vessels, before an injection тампонировали cross channels of cervical department of a spine column and the vertebral channel hygroscopic cotton wool. After fixing of a material made cranial trepanation and took a brain. Further from preparations did x-ray pictures. As a result of research established that the main sources of blood supply of a brain of a bull house are the right and left rostral and kaudalny connecting arteries formed by branching of brain carotids, and also the main brain artery. The brain carotid at a bull house originates from a wonderful vascular network of basis of a skull which is formed by merge of branches of a maxillary artery to branches of vertebral and myshchelkovy arteries. Rostral and kaudalny connecting arteries of the right and left parties of a brain, uniting with each other, I form round a hypophysis an arterial ring of a brain (Villiziyev a circle). Forward the pair rostral brain artery departs from an arterial ring at a bull house. On each side from a rostral brain artery each rostral connecting artery from both parties gives a rostral artery of a brain cover and an average brain artery. The Kaudalny connecting artery gives rise to kaudalny brain arteries, arteries a chetverokholmiya and to rostral arteries of a cerebellum. The main brain artery supplies with blood the most part of a diamond-shaped brain and is formed by merge of branches of the right and left occipital arteries. On the way the main brain artery gives multiple pair arteries of a medulla and an artery of the brain bridge. Behind the brain bridge the right and left kaudalny arteries of a cerebellum depart from the main brain artery.
