The need to understand coronary artery anatomy in detail has become ever so important because of wide variations in the anatomy and various anomalies noted in different populations. Knowledge of coronary dominance is important to understand the severity of coronary artery diseases and plan the treatment of cardiovascular diseases. It determines the amount of myocardium that is perfused by the left or right coronary circulation. Materials and Methods: adult formalin fixed heart specimens were collected from routine under graduate and post graduate dissection at Belgaum Institute of Medical Sciences, Belagavi irrespective of sex and age. The origin of posterior interventricular artery was examined and dissected. Results were noted and compared with previous studies. Results: Out of 100 specimens studied in 83 (83 %) specimens the posterior interventricular artery was arising from right coronary artery and in other 17 (17%) specimens it arose from Left circumflex artery. In none of the specimens studied the posterior interventricular artery was arising from both the coronary arteries. Conclusion: The knowledge of normal anatomy and variations of coronary dominance will help interventional cardiologist, cardio-thoracic surgeons and radiologist of North Karnataka region in proper management of patients.

the culture, built of a person and many factors. Hence the anthropometric technique is exclusively used
by medical scientists and anatomists to estimate the body size since many years. The present study was
conducted to estimate the left humer al length from the measurements of proximal and distal segments of
humerus in region of North Karnataka population using regression equation. This helps in estimating the
stature of individual using standard regression formulae and tocompare these data with the study conducted
in other countries for the use in forensic and archeologicalstudies. The current study was therefore focussed
on proximal and distal segments of left humerus and using these, the length of the left humerus was
estimated.
Materials and Methods: The different measurements of proximal and the distal segments of 47 left
humeri and the mean values of the maximum length of the left humerus (MHL) were noted and used in our
study to derive the regression equation. . Maximum length of humerus, vertical and transverse diameter
of proximal segment, transverse diameter and biepicondylar width of distal segment were measured using
anthropometric techniques.
Results: With the fragment measurements obtained, regression equations for left humeri was derived to
estimate the maximum length of the humerus in North Karnataka region population. On applying the
regression analysis, among 47left humeri, it was found that, the vertical diameter of superior articular
surface had significant role in estimating the maximum humeral length with maximum correlation coefficient
of 0.87 (p<0.05).
Conclusion: The result of this study concludes that the length of the left humerus can be estimated from
the measures of proximal and distal segments of left humerus.

using the anthropometric technique to estimate the body size since decades or even centuries. The study
which we have conducted in North Karnataka of South Indian was to estimate the length of the right
humerus from the dimension of proximal and distal segments of humerus using a regression equation. This
is absolutely essential for archeologists, anthropologists and forensic investigators, even when a fragment
of bone is available. The current study was therefore focused on the measurement of proximal and distal
segments of humerus from which the length of the humerus was estimated.
Materials and Methods: The maximum lengths of the right humeri (MHL) were measured and the mean
values were calculated. The different measurements of proximal and the distal segments of 53 right humeri
were noted and used in our study. Maximum length of humerus, vertical and transverse diameter of
proximal segment, transverse diameter and biepicondylar width of distal segment were measured using
anthropometric techniques. A regression equation was formulated to calculated the length of the entire
humerus provided we can access the measurements of different fragments available.
Results: With the measurements obtained analysis was done using descriptive statistics. Regression
equation for right humeri was derived to estimate the length of the right humerus. On applying the
regression analysis, among 53 right humeri, it was proved that, the vertical diameter of superior articular
surface had significant role in estimating the maximum humeral length with maximum correlation coefficient
of 0.94(p<0.05).
Conclusion: Thus we can conclude that the length of the right humerus can be estimated from the measures
of proximal and distal segments of right humerus.

Materials & Methods: In the present study, 30 human cadavers from the Department of Anatomy, Belagavi Institute of Medical Sciences, Belagavi were examined for the variations of anterior belly of digastric muscle during routine dissections of undergraduate and postgraduate students. The variations found were neatly dissected and photographs taken wherever necessary. Result: Out of 30 cadavers dissected3 specimens presented with variations. Discussion: First variation found had a unilateral accessory belly of digastric muscle on right side. Second variation was unilateral accessory belly of digastric muscle on left side and the third variation was bilateral accessory slips of digastric muscles. The details of these variations will be dealt in the article. Conclusion: As the variations of anterior belly of digastric muscle are common, the radiologists and the surgeons have to watch out for these while deal...
