Introduction: The lung fissures define the borders of the lobes of the lungs; understanding their position is essential for understanding lobar anatomy and, as a result, finding the broncho-pulmonary segments, which is important both physically and therapeutically. Objective: This study was carried out to examine lungs morphologically and classify lung fissures based on Craig and Walker. Materials and methods: In this study, 30 cadaveric lungs were taken and examined for morphology and differentiation of fissures. Out of these 30 cadaveric lungs, 20 were males, and 10 were of females. The thoracic wall of properly embalmed and formalin-fixed cadavers was dissected, and the lungs were exposed to study the morphological features, including number, lobes, and fissures. Result: This study state 19 (63.3%) incomplete horizontal fissure in the right lungs. Interestingly this study also represents no horizontal fissure in 1 (3.3%) right lung. Whereas 9 lungs were having incomplete oblique fissure and in 2 (6.6%) there was no oblique fissure. Similarly, this study also state 12 (40%) incomplete oblique fissure in the left lung. In one lung interestingly there was no fissure. While, other right and left lungs were anatomically normal. Conclusion: According to the current study, the right lung had more partial horizontal fissures and a few right lungs had no fissures. Radiologists and surgeons must be aware of variations in lung fissures and lobes in order to minimize and reduce the mortality and morbidity associated with invasive lung procedures. Understanding the anatomy of lung fissures assists in evaluating the various radiographic manifestations of interlobar fluid. I hope that this research will be useful to all of the practitioners mentioned above
