Coronary arterial anatomy of the one-humped camel (Camelus dromedarius).
Abstract: The detailed coronary arterial anatomy of seven camels was studied and compared with that of horses and cattle. In camels, there is a bilateral coronary supply, the right coronary artery being the larger. The left coronary artery follows the same pattern as that in horses. The ramus collateralis proximalis in camels separates off some distance away from the origin of the ramus interventricularis paraconalis, as in horses, whereas it separates of very quickly in cattle. The ramus collateralis distalis has two branches in camels, whereas the left distal ventriculi ramus does not branch. The ramus angularis is also absent but the left distal atrii ramus is present.

The research studied the coronary arterial structure of seven one-humped camels, comparing it with the arterial anatomy of horses and cattle. The key findings show that camels have a dual coronary supply with a larger right coronary artery, and their coronary structure has certain similarities and differences with that of horses and cattle.
Study of Coronary Arterial Anatomy in Camels
- The study dissected the coronary arterial system of seven one-humped camels (Camelus dromedarius), marking a detailed study into a field with limited data.
- Findings revealed that the camels have a bilateral coronary supply, meaning that both the left and right coronary arteries supply blood to the heart. Notably, the right coronary artery was larger than the left coronary artery in the camels.
Comparison with Horses and Cattle
- Researchers also compared the coronary anatomy of camels with that of horses and cattle.
- In terms of similarities, it was found that the left coronary artery in camels has the same pattern as in horses.
- Another similarity with horses was observed in the case of ramus collateralis proximalis. This artery separates from the primary artery at some distance away from the origin of another artery, the ramus interventricularis paraconalis. This is contrasted with cattle, where the ramus collateralis proximalis separates off very quickly from the main artery.
Variations in Arterial Branches
- Researchers noticed variations in the branching of certain arteries in camels as compared to other studied animals.
- The ramus collateralis distalis, for instance, branched into two in camels, while the left distal ventriculi ramus remained unbranched.
- Also, the study found that the ramus angularis is absent in the species studied, but the left distal atrii ramus is present.
- These specifics provide invaluable insights into the unique coronary architecture of the one-humped camel, fostering our understanding of their cardiovascular system and potential impacts on their health and well-being.
