Sistematização da origem, da distribuição e dos territórios da artéria cerebral...

Foram estudados 26 encéfalos de gatos, adultos, sem diferenciação de sexo, sem raça definida, corados com látex e fixados por solução aquosa de formaldeído. As artérias cerebrais caudais, direita e esquerda, apresentaram-se únicas em 96,1 e 88,4% dos casos, respectivamente. Em 69,2% dos casos no antímero direito e 80,8% no esquerdo, a artéria cerebral caudal originou-se pela anastomose entre o ramo caudal da ar...

Comparative analisys of neuron densities in cortical areas of different dogs breed

They were studied and compared the neuronal densities of the cerebral cortex of three dogs races, with constitutional types, characteristic and different functional aptitudes amongst themselves. Of the brain they were solitary fragments of the different areas of the cerebral cortex, corresponding to the system limbic, visual, hearing, motor, palate, sense of smell and to the area somestesic. Through counting ap...

Morfofisiologia da inervação do diafragma de ovinos

Proposal of anatomical terminology to call the arteries of the base of the ence...

Arteries of the encephalon basis of 30 monkeys (Cebus paella) were studied. Arteries were injected with colored latex, fixed in formaldehyde solution at 10% and dissected under magnifying lenses. Since the animals died from natural causes they had been previously used in other experiments. Human and veterinary anatomical terminology and literature were used as a reference for the determination of vessels studie...

Morphologic study of the pineal gland of the dog

Following the discovery of the melatonin by Lerner et al. (1958), new research and perspectives were developed in order to improve the knowledge regarding the pineal gland. This hormone is not only related to the circadian control but also influences other behavioral functions such as the reproductive cycle and thermoregulation. In this study the morphology of the pineal gland (epiphysis cerebri) from 20 dogs w...

Estudo anatômico do cerebelo do macaco-prego (Cebus apella Linnaeus, 1758)

Morphology of the pineal gland in opossum (Didelphis sp)

The pineal gland must to be analyzed and studied in animals of the Brazilian fauna, to apply the data obtained in the basic research of new techniques at reproductive handling of these animals, including in captivity, in view of the close relation between this photoreceptor organ with the circadian and reproductive cycle. For this study, 10 opossums (Didelphis sp), had been used, already died and fixed, proceed...

Anatomic study of the Cebus paella monkey's cerebellum. Considering the importance of the cerebellum's function in the control and maintenance of body equilibrium and muscle tonus, as well as the establishment of posture, harmony and movement coordination, this work proposes to analyze, in Cebus apella, the macro- and mesoscopic morphology of its cerebellum. The aim was to achieve a better knowledge of the macr...

Anatomical study of the intrapelvic portion of ischiatic nerve in fetuses in cr...

The sciatic nerve is the largest of all nerves of the body. It emerges from the pelvic cavity through the major sciatic foramen as a wide, flat and brownish cord. It extends caudally and ventrally over the distal and lateral part of the pelvic broad ligament. There are several experimental and clinical evidences supporting that the majority of injuries affecting the sciatic nerve in bovines are associated with ...
