Anatomy and histology of the urinary tract in the capuchin monkey (Sapajus apella

Abstract:

Sapajus apella is a primate of the New World of midsize and with geographical distribution from South America to Argentina. Good models for the study and in recent years have been widely used for this purpose. The progressive destruction of the natural habitat of these animals has led to migrate to other regions, thus making them more susceptible to hunting predator. The need for the preservation of wild species arouses interest by a greater anatomic and clinical knowledge of these animals. The present study was aimed to examine and describe the morphological aspects, as far as the macroscopic and microscopic anatomy of the organs of the urinary system of female Sapajus apella aiming to extend the anatomical knowledge for this species. Four females were used, from the National Center of Primates in Ananindeua - PA. The urinary system of S. apella has similar characteristics to other primates both human and non-human and domestic animals. The kidneys showed macroscopic aspects similar to the kidneys of humans, but with the same classification of other non-human primates and some domestic animals. The bladder was similar to domestic animals and primates in general, human and non-human. The same occurred when we analyze these components histologically.
