Abstract
Ten adult mules were used in this study for gross anatomy, light and electron microscopy. The branching of the terminal portion of the common carotid artery was found to be similar to that of the horse. The carotid body of the mule is compact and located at the angle of bifurcation of the internal and external carotid arteries. Groups of cells surrounded by connective tissue capsule were clear, with light as well as electron microscopy. The amounts of electron dense granules differ in the two cell types of the carotid body (Types I and II). The carotid sinus is located at the origin of the internal carotid artery. Both the carotid sinus and the carotid body were described in detail, with their blood and nerve supply in the mule and compared to other domestic animals.
