ABSTRACT
The objective of this work was to assess the origin and distribution of femoral nerves in 30 swine fetuses from crosses of Dan Bred and AGPIC-337 lines. Thirty animalsfifteen males and fifteen femalesfrom the collection of the Faculty of Veterinary Medicine's Animal Anatomy Laboratory of the Federal University of Uberlândia, Uberlândia MG, Brazil, were used. The animals were fixed by injecting a 10% aqueous formaldehyde solution into the descending aorta artery and thoracic, abdominal, pelvic and intramuscular cavities. The specimens were then submerged in a solution with the same concentration. These animals have five to seven lumbar vertebrae. The number of lumbar vertebrae was six in 96.67% and seven in 3.33% of the animals. The femoral nerve originated from the L4 and L5 (66.67%), L5 and L6 (26.67%) and L3 and L4 (6.66%) lumbar vertebrae. It sent branches to the psoas major, psoas minor, iliac, pectineus, and quadriceps femoris muscles in all animals, to the sartorius in 43.33% and to the gracilis in 6.66% of animals. No marked differences were found in the characteristics of origin and distribution of the femoral nerve between the swine fetuses from crosses of Dan Bred and AGPIC-337 lines and the animals described in the literature.
Objetivou-se estudar a origem e distribuição dos nervos femorais em 30 fetos suínos oriundos do cruzamento das linhagens Dan Bred e AGPIC337. Foram utilizados 30 animais, quinze machos e quinze fêmeas, pertencente ao acervo do laboratório de Anatomia Animal da Faculdade de Medicina Veterinária da Universidade Federal de Uberlândia. A fixação dos animais se deu por meio de injeção de solução aquosa de formaldeído a 10% na artéria aorta parte descendente, cavidades torácica, abdominal, pélvica e intramusculares, em seguida, os espécimes foram submersos em solução contendo a mesma concentração. Esses animais possuem cinco a sete vértebras lombares. Em 96,67% dos animais o número de vértebras lombares foi seis e em 3,33% sete. O nervo femoral originou-se de L4 e L5 (66,67%), L5 e L6 (26,67%) e L3 e L4 (6,66%). Emitiu ramos para os músculos psoas maior, psoas menor, ilíaco, pectíneo, quadríceps femoral em 100% dos casos, 43,33% para o sartório e 6,66% para o grácil. Nota-se que não foram observadas diferenças marcantes nas características tanto na origem como na distribuição do nervo femoral entre os fetos de suínos oriundos do cruzamento das linhagens Dan Bred e AGPIC337 e os animais da literatura consultada

In the present study, the myocardial bridges of an adult, female, mountain lion that died of natural causes at the "Parque do Sabiá" Zoo, Uberlândia, Minas Gerais, Brazil were examined. The heart was fixed in a 10 por cento formalin solution and the coronary arteries were injected with neoprene latex 450(R). The myocardial bridge is a superficial muscular band that crosses a short segment of the coronary arteries on the epicardium various localizations in the heart. Twelve bridges were seen in this heart. Three crossed the first branch, five crossed the second branch and four crossed the fifth branch of the paraconal interventricular branch of the left coronary artery. The average length of the myocardial bridges was 2,08 mm (range 0,80-3,95 mm), the length of the left ventricle was 58.3 mm. Of the bridges examined 58,3 por cento were in the medial third ventricle, 33,3 por cento were in the apical third and 8,3 por cento were basal third.
