The origins, ramifications and distributions of the left and right facial arteries were studied in 30 stillborn pigs (Sus scrofa domesticus) of the Sadia lineage, 17 males and 13 females, with the aim of increasing morphological knowledge of these structures in terms of their localization and distribution. The species was chosen for its well known commercial importance. The specimen had its artery system filled with stained solution of neoprene latex 601 A and afterwards fixed in an aqueous solution of formaldehyde at 10%. It was observed that in 100% of the studied animals the facial arteries originated from the ventrolateral surface of the external carotid artery, rostrally to the lingual artery. The gland branches divided, supplying the mandibular, parotid, monostomática portion of the sublingual and part of the cervical thymus in muscular branches, irrigating the medial pterygoid, masseter, ventral aspect of the digastrics and cutaneous of the face muscles. Furthermore, the pharyngal branch irrigated the soft palate, tympanic bula and basihyoid, and the submentalis artery was directed towards the submental and the dorsal face of the digastrics muscles.
