The excretory system of the liver in wild animals. VI. Biliary ducts of the great anteater (Myrmecophaga tridactyla)

Neste trabalho säo sistematizadas as vias bilíferas do tamanduá bandeira (Myrmecophaga tridactyla). Os resultados demonstram: o ductos choledocus, livre de afluentes, origina-se da uniäo do ramus principalis dexter e do ramus principalis sinister. O ramus principalis dexter é invariavelmente composto pelo ramus lateralis lobi dextri e pelo ramus medialis lobi dextri, enquanto o ramo pincipalis sinister está composto pelo ramus lateralis lobi sinistri, ramus medialis lobi sinistri e ramus lobi quadrati

[Topography of the blood vessels in the hilum of the kidney of Myrmecophaga tridactyla]. / Topographie des vaisseaux sanguins au hile du rein du (Myrmecophaga tridactyla).

The study was undertaken in 10 formol-imbibed kidneys of great anteater (Myrmecophaga tridactyla). After the dissection the following characteristics were showed: kidney blood vessels are distributed in 2 different sites, namely hilar and extrahilar, amounting 3 to 6 in the right side 3 to 7 in the left side. Arterial branches in extrahilar region range from 1 to 2 in both sides and in hilar region they present from 1 to 4 in the right and 1 to 2 in the left. Venous roots occur in 1 to 2 vessels in the right and 1 to 3 vessels in the left, occupying only the hilar region, except one case where it was present in the right side.

The animals came from the Region of the Alta Araraquarense. The spicules of the worms were well chitinized and measured, on the average, 153,68 micrometer with a standard error of 0,91 micrometer.
