ABSTRACT

 

Paryani MR, Kianfar H., Morphology of lung and trachea in long-eared hedgehog (Hemiechinus auritus), Onl J Vet Res., 21(6):328-334, 2017.  Five long-eared adult male hedgehogs without respiratory disease were used. After euthanasia, tracheal bifurcation was set with a pin in dorsal and lateral recumbency and lobes were inflated by syringe. Lungs showed no pleural blebs, edema, or infection. Lung volume was determined by weight displacement. Cranial cervical ring caudal to cricoid cartilage, caudal cervical ring at point of thoracic inlet and caudal thoracic ring cranial to tracheal bifurcation measurements, were recorded. Tracheal rings were counted on digital image. Tracheobronchial tree and lungs were injected with Rhodopas color resin through larinx plastic cannula, solidified for 24h, and then macerated with concentrated HCl. We find that cartilage rings varied 10 to 11 in cervical and 6 to 10 in thoracic regions. Rings were oval with cross-section diameter of 3.67 ± 0.077mm and dorso–ventral of 2.24 ± 0.14mm. Trachea bifurcated right and left between the 2nd and 3rd rib. The right principal bronchus branched into 4 lobar cranial, caudal, middle and accessory  bronchi. The left principal bronchus did not have lobar branches and branched directly into several tertiary bronchioles. The right lung had 4 lobes but the left lung, only 1. In conclusion, the respiratory system in hedgehogs is similar to mice. Findings are supported by images.
