Arterial Patterns of the Face in Perissodactyla.
Abstract: Considerable consistency in the arterial pattern of the head has been observed in species of Artiodactyla, but few studies have examined the order Perissodactyla. Here, we describe arteries supplying the intermandibular, mental, masseteric, buccal, labial, and nasal regions in eight perissodactylans, including representing of all families comprising this order. Observations were made on a total of 45 preparations of head arteries, obtained by injection of arteries with acetone-dissolved stained vinyl superchloride or stained latex LBS3060. In the Equidae species alone it was found that the facial artery descends from the linguofacial trunk. In tapirs and rhinos the facial artery branches off directly from the main arteries of the head. In tapirs alone it was found that the inferior alveolar artery gives off the buccal and sublingual arteries, and then extends into the mental artery. In the rhino a specific feature of the arterial pattern of the head was the exit of the occipital artery from the superficial temporal artery. In all equines studied, the transverse facial artery gave off a larger blood vessel to the masseter muscle and ran along the facial crest, while in tapirs and rhinos the transverse facial artery fanned out branches in the masseteric fossa. The variations observed can be considered in future studies on the origin of Perissodactyla. In this context, we note that the most similar patterns of exit and course of the facial, mental, transverse facial and infraorbital arteries exist in tapirs and rhinos (Ceratomorpha suborder), at least among the perissodactylans studied here.

The research article discusses the unique arterial patterns found in the heads of various Perissodactyla species, including horses, tapirs, and rhinoceroses. These patterns were observed through different staining methods which highlight the blood vessels.
Research objective and method
- The researchers wanted to describe and observe the arteries in the faces of different Perissodactyla, an animal order that includes species such as horses, tapirs, and rhinos. Their goal was to better understand arterial patterns to facilitate future anatomical and physiological studies.
- Researchers analyzed a total of 45 head artery preparations from different Perissodactyla species. These preparations were obtained by injecting the arteries with acetone-dissolved stained vinyl superchloride or stained latex LBS3060. This allowed detailed observation of the arterial patterns.
Main findings
- In horses (Equidae species), the facial artery was found to descend from the linguofacial trunk, a major artery in the head and neck.
- In contrast, tapirs and rhinos showed a different pattern where the facial artery branched off directly from the main arteries of the head.
- Another unique trait found in tapirs was the inferior alveolar artery extending into the mental artery after giving off the buccal and sublingual arteries.
- For rhinos, a notable feature was the occipital artery exiting from the superficial temporal artery.
- In all studied horse species, the transverse facial artery ran along the facial crest and provided a large blood vessel to the masseter muscle. In tapirs and rhinos, the transverse facial artery fanned out branches in the masseteric fossa, an area on the face near the lower jaw.
Implications and Conclusions
- The observations can guide future research on the evolution and ontogeny of Perissodactyla, as these arterial patterns can serve as anatomical markers.
- Notably, similar patterns of certain arteries were observed between tapirs and rhinos, both part of the Ceratomorpha suborder. This may be significant for evolutionary studies within this suborder among the Perissodactylans.
