Abstract: The aim of this study is to review of carotid body location and nerve and blood supply. In this study Heads of eight cattle of different sexes were collected from Uremia abattoir. By simple dissection method, definite position and nerve supply of the carotid body. Before dissection, colored gelatin was injected into right and left common carotid artery. According to this technique all the branches of common carotid artery and the branch which supplies into carotid body were investigated. This investigation revealed that, the carotid body of cattle is situated around the occipital artery and it is made up of compact portion only. Its blood supply is by glomic artery which is a branch of occipital artery. Its nerve supply is by herring nerve which is a branch of glossopharyngeal nerve. The carotid body in cattle was found close to the origin of occipital artery similar in sheep, buffalo.
