Morphologic Observation of the Left Coronary Artery of Goat

Objective To explore the anatomic feature of the goat’s left coronary artery, enrich the animal experimental data. Method To execute the ninety goats used in the experiments of surgery operation and take the hearts into 10% formaldehyde.Six left coronary artery was exposed and was injected with reagent mixed with chloroethylene, acetic acid and ethanol to make into artery vessels strickle. At last,the left coronary artery and its branches were measured and dealed statistically. Results The goat heart coronary artery falls into the left and right coronary, the left one is bulky and superfacial, its anterior interventricular branch goes on the cardial muscle suface or into the cardial muscle which is not seen clearly often covered by the cardiac muscle bridges. Its circumflex branch is bulky and goes long distance with more branches. Between the anterior interventricular branch and the circumflex branch the diagonal branch often appears. The left coronary of goat is predominant. Conclusion The goat’s coronary artery is much different from that of human.
