Introduction: In human anatomy the acetabulum is a cavity on the lateral aspect of the hip-bone. The purpose of this study is to record the depth and diameter of the acetabulum cavity to accumulate morphological data helpful for anthropologists, Forensic medicine experts and orthopedicians. Materials And Methods: The study was done on 88 adult human hip bones (42 right and 46 left) collected from Department of Anatomy, Govt.T.D Medical College, Alappuzha, Kerala state. The diameters and maximum depth were measured using digital vernier calliper. The measurements were compared with other studies in the world. The mean diam Results: eter of acetabulum was 48.08 ± 3.21mm, 44.16 ± 2.60 mm in male and female respectively. The mean ± S.D value of depth was 29.11± 2.37 and 27.20± 2.01 mm. in male and female respectively. The correlation between depth and diameter was signicant only in the right male hip bones. There is signicant variation in the Conclusion: anatomical parameters of hip bone between different Indian population groups. The data from this study may be used for designing population specic hip prosthesis.

BACKGROUNDTen bronchopulmonary segments are described for each lung. Foreign bodies and other aspirated materials tend to enter the right instead of the left bronchus, because the former is wider and more in continuation with the trachea and from there to the apical bronchus of the lower lobe. So the right lower lobe was selected for a study by dissection. The bronchopulmonary segments of inferior lobe of right lung are 5 in number-superior (apical), medial basal, anterior basal, lateral basal and posterior basal. Some workers consider an occasional segment, which arises as a separate bronchus from the right inferior lobar bronchus below the apical bronchus, which they term as subapical segment.
