Morphology and Vascularization of the Gastric Compartments in Three-Toed Sloth (Bradypus torquatus Illiger, 1811)

The macroscopic anatomy and vascularization of the stomach compartments of Bradypus torquatus were examined in five animals from the University of São Paulo College of Veterinary Medicine and Zootechny collection. The method included aqueous perfusion of the arterial network, colored latex injection...

A Digestive tract Stomach Celiac artery Bradypodidae Xenarthra The macroscopic anatomy and vascularization of the stomach compartments of Bradypus torquatus were examined in five animals from the University of São Paulo College of Veterinary Medicine and Zootechny collection. The method included aqueous perfusion of the arterial network, colored latex injection, fixation in formaldehyde (10%) and preservation in Laskovisk solution. Dissections were performed under mesoscopic light and photo documentations were performed for description and data analysis. In these animals, the largest abdominal organ was the stomach, which internally presented the cardiac, fundic and prepyloric regions, subdivided in six compartments (cardiac right, middle and left; fundic; pre-pyloric I and II). The stomach was irrigated by the left gastric and celiac arteries, which are ventral visceral branches of the abdominal aorta. These arteries emerged in the retroperitoneal region and reached the viscera through the mesogastric region, distributed in the large and small stomach curvatures, in the spleen and the pancreas. The primary collateral branches of the left gastric artery are directed to the large stomach curvature, and the celiac artery irrigated the spleen, the pancreas and the small stomach curvature.
