title: Comparative analysis of the course of the facial and transverse facial arteries in selected ruminant species.
abstract: The paper describes variations in patterns of origin from the main arteries as well as of branching and course demonstrated on the basis of selected facial arteries in several species of ruminants. The studies included 35 species of 27 genera, 9 subfamilies of animals belonging to families of Bovidae, Cervidae, Giraffidae and Moschidae from the suborder of Ruminantia, including species maintained by humans. Altogether, 435 preparations of head arteries were studied. Arteries of the examined animals were filled with acetone-dissolved stained vinyl superchloride or stained latex LBS3060. The facial artery was found to originate from the main arteries of the head in three different manners. In species devoid of facial arteries, the presence of a pronounced transverse facial artery could be demonstrated. Division of the animals into large and small ruminants, generally accepted by authors of animal anatomy textbooks, was found to be oversimplified and lacking in universal character, as to the patterns of origin and course of the facial artery and the transverse facial artery.
