Myocardial bridges (MBs) are cardiac abnormalities in which segments of coronary artery are embedded in myocardium. They are considered normal in adult dromedary camels. This study aimed to investigate the existence and morphology of foetal myocardial bridges in dromedary camels. 30foetuses obtained from Tambul and Al-Salam slaughterhouses, Sudan, were used in the study. They were divided into three equal groups: first trimester, second trimester and third trimester. Anatomical, histological and morphometric studies on myocardial bridges over descending branches of the coronary artery were done. MBs were absent in the first trimester, but they appeared frequently in the late and early stages of the second and third trimesters. They were in the form of parallel bundles of cardiac muscle fibres separated from the branches of coronary artery by loose connective tissue. The walls of MBs and descending interventricular branch of coronary artery were significantly thicker in the third trimester than those in the second trimester. It could be concluded that (MBs) are normal in camel foetus in the first and second trimesters; they increased in thickness with the increase in the foetal age.
