Abstract
The common marmoset (Callithrix jacchus) are small primates belonging to the family Cebidae, subfamily Callitrichinae and are the most well-known and common in adaptation to captivity. The scarcity of data in the literature on the anatomy of these marmosets and wild animals hinders the application of appropriate anesthetic and surgical procedures and therapeutics. In order to understand the anatomic variations in the lobation and bronchopulmonary segmentation the lungs were dissected from nine adult common marmoset (Callithrix jacchus) corpses, five males and four females. In the marmosets, the right lung presented cranial lobe, middle lobe, caudal lobe and accessory lobe while the left lung presented cranial and caudal lobes. The fissures were very pro-eminent in both the lungs. The main right bronchus emitted independent branches, one for each lobe, and it followed in a straight line in the caudal lobe as a continuation of this bronchus and the same was observed in the main left bronchus. The bronchopulmonary segmentation in the right lung ranged from one to five branches in the cranial lobe; the middle lobe had a single branch; the caudal lobe had three to five branches and the accessory lobe had three branches. In the left lung the cranial lobe bronchopulmonary segmentation ranged from one to five branches while in the caudal lobe it was three to four branches.
