ABSTRACT
The thoracic part of the ferret's trachea is comparatively long to meet the relatively long thoracic cavity. This part of the trachea extends from the level of the 7th intercostal space, where it bifurcates into two bronchi principalis dorsal to the base of the heart. The bronchus principalis sinister gives off bronchus lobaris cranialis and continues as bronchus lobaris caudalis, while the bronchus principalis dexter gives off bronchus lobaris [cranialis, medialis and accessorius] and continues as bronchus lobaris caudalis. Each bronchus enters the corresponding lobe at its hilus which located in craniodorsal aspect of each lobe. The lungs of the ferret are relatively large and the left lung has two lobes [cranial and caudal], while the right lung has four lobes [cranial, middle, accessory and caudal]. Generally, all the lobes of the ferrets lungs are completely separated, except their attachment only through the bronchi and blood vessels

In this work, the anatomical features of the A. pudenda interna in the mule was studied in details, concerning the origin, course, distribution as well as its termination. It can be concluded that the internal iliac artery in the mule follows the long pudendal type resembling those found in the horse. The internal pudendal artery of the mule has many characteristic features differentiating it from that of the latter animal, including that the Aa. vesicalis media, uretericus media as well as the R. articularis of the hip joint were recorded in the studied animal. However, these arteries were not mentioned in other domestic animals including the horse. On the contrary, the A. rectalis media of the other domestic animals was not recorded in the mule. Although the A. dorsalis penis in mule and horse originated from the internal A. pudenda in the mule, this origin took place within the pelvic cavity and in the horse extrapelvic
