The Pattern Comparison of Changes of Heart Macro-Structure in the Fowl

摘要

Understanding early heart tissue structure, especially the properties of heart morphology is ofcardinal interest for varied biomedical disciplines. During the past few years, striking progress has been madein identifying morphology and anatomy of bird's heart; but an exhaustive study is not available about avianheart structure related to gender differences. The current study was designed to determine whether sex effectsacutely to change heart tissue pattern. Hence selected 20 native adult fowl (to equal number of both sexes) ofShahrekord districts and then hearts were dissected. Heart weight, length and diameter and thickness of leftand right ventricles were determined after preparation of tissue sections, myocardial and epicardial layers weremeasured by micrometer. With respect to the gender, gross and microscopic morphological aspects, indicatedno difference between heart weight and length and right ventricle thickness as well as left and right epicardiumin both sexes. However, thickness of the left ventricle and myocardium and heart diameter in males exceeds thatof females.
