Anatomy of Porcupine trachea and lung

Porcupines are small to medium size rodentian. This animal could be found in the north of Iran in large numbers. The aim of the present investigation was to study the anatomy of the trachea and lungs of this rodent. For this purpose, the cadaver of 3 porcupines that had been died in accidents, were dissected. The number of the tracheal rings was36 to 38. The tracheal ring was C shape and the dorsal part of them were filled by a membrane. In Tracheal bifurcation, the terminal end of the tracheal ring had been falling apart and space had been filled with an elastic membrane. The right lung included cranial, middle and caudal lobes with the length of 93.3, 48 and 67.79 respectively. The cranial and caudal lobes had cranial, middle and caudal parts and the middle lobes had cranial and caudal parts. The left lung had cranial and caudal lobe with the length of 90.69 and 72.78 respectively. The cranial lobe had the cranial and caudal part and the caudal lobe had cranial, middle and caudal lobes. In addition, the length of the right lung was larger than the left lung. The result of this study revealed that although the porcupine in a member of the rodent family, its respiratory system had its own characteristics.
