Through the right hemisphere

Through the right hemisphere one cut is made only; the line with a finger shows a direction of the second cut. The corpus collosum is cut in the field of columns and its right leg and cast away to the left. The worm of a cerebellum is dissect, its hemispheres are cast zanaflex online away in the parties thanks to what IV ventricle is opened. Through the left hemisphere of a cerebellum the first cut is made; black lines show a direction of the same cut of the right hemisphere and additional cuts of the left hemisphere of a cerebellum. Cross-section black lines correspond to places of a section of grey knots "the bases and to a brain part. in connection with visual hillocks by means of habenula (bridles). Write down its colour, size, measuring by a ruler; a kind on a cut; separate and weigh. Normally it of krasnovato-grey colour, is surrounded pia mater, at newborns consists of lobes. In its tissue there are calcareous kernels (cerebral sand), defined by touch. 55 7 Now grasp index and big fingers left the right leg of a crest falling to a back horn of the right lateral ventricle, dissect it from top to down and throw together with a corpus collosum, a crest and a vascular plexus to the left.
Thus completely open: a surface of the big grey knots, III ventricle and a surface . Examine and cautiously feel, finding out a consistence of these formations, and note a condition of III ventricle as it is told about the lateral After that it is possible to make face-to-face cuts the knife moistened with water through grey knots and to them white substance. For this purpose it is necessary to bring the left arm a palm up under the basis of a brain and over it to dissect a brain frontally on slices in the thickness of 0,5 sm, slightly raising a brain the left arm; thus slices easily are parted and become accessible to survey of a surface of cuts Now, having moved the left arm under the part of a brain and under a cerebellum and slightly raising them, a cut is dissected by a worm of a cerebellum but an average line - cerebellum hemispheres thus depart from each other in the parties and "IV ventricle opens. it also describe, as well as previous. It is necessary to do this cut especially cautiously not to cut a bottom of IV ventricle. For opening l - and in and a waterpipe also cautiously do a cut through . Dissect each hemisphere of a cerebellum half-and-half from a surface of a cut of a worm on an average branch arboris vitae. If necessary it is possible to spend the same additional cuts of each of half of cerebellum. At last, open a brain part with face-to-face (cross-section) cuts. For this purpose the left arm from below raise it above that cerebellum hemispheres have dispersed as much as possible in the parties and downwards. Cuts spend a scalpel, holding it as the writing feather, is possible cheap tegretol more abruptly These receptions it is possible to spend accurately cuts with legs of a brain, an oblong brain with 56 Bridges and through an initial part of a spinal cord, izvle-chennogo together with head. doing excessive damages. It is possible to open a part of a brain and from the brain basis. For this purpose result all ' in a starting position, that the way quite supposes. CL Rice 18 Cuts brain parts. /, 2, cut 3-lines, a-b-os a brainstem Having clasped arms both hemispheres of a brain, cautiously overturn its basis up and do face-to-face cuts through brain legs, the bridge and an oblong brain. In all time of opening of a brain carefully examine substance of a brain on cuts and describe a degree of wetness (moderated, strong, puffiness or dryness), (a hyperemia or an anaemia). At stagnation of blood it acts on a surface of a cut in the form of the points which are easily washed off (it they differ from hemorrhages). Further note colour of a cortex, knots and white substance, note a consistence - soft or is more dense. Note a condition of gyruses and sulcuses, a thickness of a cerebral cortex and a cerebellum. There can be protrusions or retractions, 4 hematomas, cysts, 57 Abscesses, tumours, tyromatoses and other changes. "For research brain parts horizontal cut is a little suitable, as at it the part is dissected under an acute angle to its longitudinal axis that breaks a segmentary order. Therefore for conservation of position of kernels and fascicles and the subsequent correct orientation a beam - Fig. 19. The Same, that on fig. 18, but a cut to do brain cuts perpendicularly to a longitudinal axis (fig. 18 and 19) a brainstem (oblong see, average and intermediate). It can be reached, doing three cuts preliminary fixed, but not deformed brain: I - through border the bridge and an oblong brain in a direction to fiss calcarinae; II - in parallel this cut behind corpora mammillaria through brain legs to the top third fiss parietooccipitale; III-also in parallel these cuts ahead and behind forward branches sulcuses through forward parts of visual hillocks The brain can be fixed and before skull opening, filling in it of 10 % formalin solution through carotids. It is possible to recommend this way especially 58 For children's corpses as the brain of children is extremely gentle also unstable easily breaks up. Pituitary body usually investigate separately. Having written down its configuration, the sizes and weight, make its opening that is recommended to do by two parallel cuts in a frontback direction sideways from a funnel. the cut through a funnel spoils an organ that for microscopical research its most valuable average part will be lost. a gland (glandula pinealis s. epiphisis cerebri) lays over lobbies under the platen of a corpus collosum at a back wall of III ventricle and it is bound to visual hillocks a leg or a bridle (habenula). It well opens at a horizontal cut of a brain on . At children it is larger, than at adults, and at women is larger, than at men. Its involution comes already at seven-year age. At its tissue often there are calcareous adjournment.
