Résumé

Among the anatomical techniques developed to obtain dry material, the cryodehydration is an important procedure, since it is very helpful in pratical classes. By alternating freezing and thawing (FT) sctions, the cell destruction simplifies fluids release, obtaining material with some advantages such as: form keeping, loss of weight, no need for fixer (no mucosal irritation) and a low cost technique.

Résumé

Because of the functional importance of the Papillary Muscles (PM) we conducted this study on the blood supply of these structures in the right ventricle. The main vessels of the musculli papillares parvi are the ramus septalis of the ramus interventricularis subsinuosus (RSSS), helped by the ramus septalis of the arteria coronaria dextra (RSCD) and the first ramus septalis of theramus interventricularis paraconalis (RSPC). Themusculi papillares magnus receives vessels mainly from theramus ventricularis of the a. coronaria dextra (RVCD) associated with the RSPC, or RSSS. Themmusculus papillaris subarteriosus receives vessels only from the RSCD. In each papillary muscle there is an arterial circle (a double blood supply), which is an anatomical arrangement protecting these structures against vascular problems.

Résumé

Tendo em vista a importância da vascularizaçao do Sistema de conduçao do coraçao e de informaçoes contraditórias existentes nas publicaçoes, dissecamos 50 coraçoes de bovinos da raça Hereford (25 machos e 25 fêmeas) injetados com neopreme Látex 450. Dividimos o território agrupado pelo Nó e Fascículo Atrioventriculares em três segmentos de igual tamanho e verificamos que o terço caudal e cranial deste Nó é irrigado pelo Ramus ventricularis dextri e o Fascículo é nutrido por este vaso e pelo primeiro Ramus septalis da A.coronaria dextra.

Résumé

Nesta publicaçao descrevemos uma técnica de conservaçao de músculos, desidratados mediante a realizaçao de sessoes de congelamento e descongelamento. O material assim preparado pode ser aplicado no estudo de anatomia veterinária e humana, apresentando vantagem de fácil acondicionamento, grande perda de peso (em torno de 60 por cento) e grande durabilidade.
