ABSTRACT

The objective of this study is to describe the cranial and caudal mesenteric arteries in 10 opossuns after Neoprene latex injection. The cranial mesenteric artery arises from the abdominal aorta, caudally to the celiac trunk, originating the caudal duodenal pancreatic artery, middle and right colic, jejunal and ileocecocolic arteries. The caudal mesenteric artery arises from the aorta, cranially to the external iliac arteries, originating the cranial rectal and left colic arteries.


El objetivo de este estudio fue describir las arterias mesentéricas craneal y caudal de 10 zorrillos después de la inyección de látex Neoprene. La arteria mesentérica craneal tiene origen en la aorta abdominal, caudalmente al tronco celíaco y da origen a las arterias: pacreáticoduodenal caudal, cólica media derecha, yeyunales e ileocecocólica. La arteria mesentérica caudal con origen en la aorta, cranealmente a las arterias ilíacas externas, da origen a las arterias rectal craneal y cólica izquierda.

ABSTRACT

Os tatus são animals pertencentes à família Dasypodidae (Ordem Xenarthra). Possuem uma carapaça dorsal bem desenvolvida, pela qual são facilmente identificados. Este trabalho teve por objetivo descrever as estruturas mais relevantes do encéfalo do tatu-galinha (tatu-de nove-bandas) (Dasypus novemcinctus), a fim de contribuir para o conhecimento da anatomia dessa espécie e, assim, entender algumas de suas funções biológicas. Foram utilizados 5 animals, cujos crânios foram separados do restante do corpo e fixados em solução aquosa de paraformaldeído (formol) a 20%, na qual os espécimes foram mergulhados durante 30 dias. Os encéfalos foram conservados em nova solução de formalina a 20% durante tempo suficiente, até que se fizessem as análises morfológicas. O encéfalo dos tatus contém todas as estruturas encontradas nos mamíferos. O telencéfalo é liso, porém apresenta rudimentos de sulcos. O cerebelo é grande, em relação aos hemisférios cerebrais. O bulbo olfatório é bastante evidente nesses animals, sugerindo uma orientação espacial pelo olfato.


The armadillos belong to the Dasypodidae famiIy (Xenarthra order); they are diggers and nocturnal. This article had aimed at describing the most evident structures of the brain of the Dasypus novemcinctus, in order to contribute to the knowledge of such species, thus understanding some of its biological functions. Five animals were used for this study; they were beheaded, and their brains were put into 20% formalin aqueous solution where the specimens were kept for 30 days. The brains were kept in a new 20% formalin solution for enough time until we did the morphological analysis. The brains of armadillos present all the structures found in mammals. The brain hemispheres are smooth, but with some circumlocutions. The cerebellum is prominent in these animals, which suggests a spatial orientation through olfact.

ABSTRACT

The biceps femoris was analyzed in 10 volunteers during knee extension and flexion with the foot in normal plantar flexion and dorsal flexion positions. Hewlett-Packard surface electrodes, an electromyographic signal amplifier, a computer equipped with an A/D conversion plaque (Model CAD 10/26), software especially designed to record and analyze the signals, Horizontal Leg Press equipped with four platforms for the feet (2 superior and 2 inferior) which acted as a support for the movements and electrogoniometers were used. The biceps femoris muscle acted as an antagonist in knee extension, primary motor of hip extension and flexor of knee joint. The upper platforms of the Leg Press required the strongest activity from the biceps femoris in relation to the lower platforms. As for bilateral action, the activity of the right biceps femoris predominated over the contralateral muscle action in all plataforms. Foot positions did not interfere in biceps femoris action.

ABSTRACT

O músculo pectíneo do gato (Felis domestica) classifica-se como bíceps e apresenta forma laminar. Relaciona-se diretamente com o nervo safeno, com os vasos femorais e com os músculos vasto medial, adutores e íliopsoas. Participa na formaçäo do assoalho do trígono femoral, constituindo seu limite caudal. A origem de sua cabeça medial se faz através de um tendäo junto à bainha do músculo reto do abdome, no tendäo pré-púbico. A origem lateral, descrita macroscopicamente como sendo feita através de fibras musculares, numa observaçäo microscópica apresenta-se inserida por microtendöes junto à eminência ílio-pbica
