Abstract:
Present study on the gross morphology and morphometry of coronary arteries in goat (Capra hircus) established that the left coronary artery (LCA) and right coronary artery (RCA) arose from left and right coronary sinuses. The oval and circular left and right coronary ostium respectively were located in the left posterior and right anterior coronary sinuses below the sinutubular junction. The mean diameters of the left and right coronary ostia were 0.46 ± 0.01 cm and 0.25 ±0.01 cm respectively. The two main branches of LCA were left anterior descending (LAD) and circumflex branches (LCx). The branches of RCA were circumflex, conal, proximal and distal branches of right atrium, intermediate, proximal and distal branches of right ventricle and marginal branch. Several other sub- branches were given by LAD and LCx. The mean lengths of LCA and RCA were 1.11 ± 0.02 cm and 6.68 ± 0.13 cm respectively.
