Summary: | 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.
Resumo: Os saguis-de-tufos-brancos (Callithrix jacchus) são pequenos primatas que pertencem à família Cebidae, subfamília Callitrichinae e são os mais conhecidos e comuns na adaptação ao cativeiro. A escassez de dados disponíveis na literatura sobre a anatomia desses saguis e de animais silvestres dificulta a aplicação de procedimentos anestésicos, cirúrgicos e terapêuticos apropriados. Visando conhecer as variações anatômicas da lobação e segmentação broncopulmonar foram dissecados os pulmões de nove cadáveres de saguis-de-tufos-brancos (Callithrix jacchus) adultos, sendo cinco machos e quatro fêmeas. Nos saguis, o pulmão direito apresentou lobo cranial; lobo médio; lobo caudal e lobo acessório; e o pulmão esquerdo os lobos cranial e caudal. As fissuras são bem proeminentes em ambos os pulmões. O brônquio principal direito emitiu ramos independentes, um para cada lobo, sendo que no lobo caudal seguiu em linha reta como a continuação deste brônquio e o mesmo foi observado no brônquio principal esquerdo. Em relação à segmentação broncopulmonar, o pulmão direito apresentou no lobo cranial |
