“…The good performance of these mechanisms as well as the anatomical integrity of laryngeal cartilages is necessary for its normal functioning. The cartilages present in the larynx are different in number and shape in the domestic and wild species (Aravena et al, , Bertassoli et al, , Hare, ; Oliveira et al, , Silva et al, ; Souza Júnior, Carvalho, Mattos, Anjos, & Santos, ).…”

Armadillos, Xenarthras representatives, known for adaptability to different ecosystems, own specific morphophysiological characteristics that are not known and deserve to be studied. The aim of this study was to describe the morphology of cartilage of the larynx of the nine-banded armadillo (Dasypus novemcinctus). Five dead armadillos were donated by the Chico Mendes Institute of Biodiversity (ICMBio-PI) to the Federal University of Piauí. The animals were fixed and dissected for removal of the larynx. The cartilages were identified and described, photodocumented, and schematized. Fragments with about 0.5 cm of each cartilage were collected and submitted to classical histology for Hematoxylin-Eosin coloring. The slides were assembled in enterlan and analyzed under a light microscope. The larynx of the armadillo (D. novemcinctus) is located in the mentonian region, ventral to the esophagus, and due to the total positioning of the tongue in the oral cavity, there is also a cranial cervical position in this species. The larynx has five cartilages, they are: a cricoid, a thyroid, an epiglottis, and two arytenoids. The corniculate process is present; however, the cuneiform process is absent. The epiglottis has a discrete bifurcation at its apex. In all cartilages epithelial variations are observed. The tissues are varied from squamoso stratified to cylindrical pseudostratified, with propria lamina rich in mucoserosas glands. With the exception of epiglottic cartilage, predominantly elastic, the rest are hyaline. The larynx of D. novemcinctus, although the same number of cartilages, differs morphologically and microscopically from the larynx of other species.

“…Em Didelphis sp. situa--se ventralmente ao atlas e áxis (Bertassoli et al 2013) enquanto na Dasyprocta sp. posiciona-se na região cervical caudal devido ao maior comprimento da língua (Silva et al 2014).…”

“…Segundo Bertassoli et al (2013) há epitélio pseudoestratificado respiratório na região caudal da epiglote em Didelphis sp., o que não foi visto em C. thous. A presença de glândulas mistas tubuloacinares na lâmina própria da epiglote de C. thous também foi relatada em animais domésticos por Banks (1991) e Bacha & Bacha (2000) e em Nasua nasua por Oliveira et al (2011).…”

Por outro lado, análises detalhadas da laringe humana já foram bem documentadas (Maue & Dickson 1971, Eckel et al 1994.…”

Resumo: Cerdocyon thous (cachorro-do-mato) é o canídeo silvestre mais comum em território sul-americano. Objetivou-se com o presente trabalho descrever a morfologia macroscópica, microscópica e comparada da laringe nesta espécie. Para tal, as laringes de dezesseis espécimes (quatro machos e doze fêmeas) foram analisadas quanto à topografia, forma, morfometria, musculatura intrínseca e histologia. A laringe dispôs-se ventralmente ao áxis e foi constituída por uma cartilagem tireoide e outra cricoide (hialinas), uma epiglótica (elástica) e um par de ariteoides (mistas). Um par de cartilagens sesamoides foi identificado entre os processos corniculados e a lâmina da cricoide. A morfometria revelou que a tireoide é a maior cartilagem. Não houve sinais definitivos de dimorfismo sexual na laringe de C. thous. O epitélio predominante foi do tipo pavimentoso estratificado o qual sofreu transição para pseudoestratificado cilíndrico ciliado ao nível do terço caudal da tireoide e rostral da cricoide. A laringe de C. thous mostrou semelhança com a do cão doméstico, ainda que o formato das cartilagens tenha apresentado diferenças.

Rodents are important in the transmission of infectious diseases that affect the respiratory tract, including simple infections and those caused by specific pathogens. These animals are natural reservoirs of zoonoses that cause many public health diseases. Basic knowledge on the morphology of these animals is important as basic research is useful for applied studies, such as the development of clinical, therapeutic, surgical and clinical models. Morphological data of respiratory tract in Oligoryzomys nigripes are absent in the literature. Therefore, the aim of this study was to perform a morphological analysis of the respiratory tract of O. nigripes. Five adult females from the environmental reserve in São Joaquim da Barra, São Paulo were used, donated to the Museum of Veterinary Anatomy (FMVZ/USP). Several morphological features follow the same pattern seen in rodents; however, this species showed some differences such as the presence of three lobar bronchi, nonlobed left lung and the right lung constituted by two lobes. Respiratory epithelium lined the whole respiratory tract and was seen using scanning electron microscopy the oval shape of the parenchyma and alveoli.
