Origens, ramificações e distribuições das artérias faciais em suínos (Sus scrofa domesticus Linnaeus 1758) da linhagem sadia

Abstract

Origins, ramifications and distributions of the left and right facial arteries were studied in the 30 (thirdy) stillborn swines (Sus scrofa domesticus) of the Sadia lineage, 17 (seventeen) males and 13 (thirteen) females. The specimen had it s artery system filled with stained solution of neoprene latex 601 A and after wards attached in a wattery solution of formaldehyde at 10%. It was observed that in 100% of the animals studied the facial arteries originated of the ventrolateral surface of the external carotid artery rostrally to the lingual artery. The gland branches ramificated supplying the mandibular, parotid glands, monostomatica portion of the sublingual gland and lobos of the cervical thymus in muscular branches irrigating the medial pterygoid muscle, masseter, ventral aspect of the digastric muscle and cutaneous of the face. Furthemore, the pharyngitis branch irrigating the soft palate, the tympanic bula and basihyoid, and last but not least the submentalis artery that is directed towards the submental muscles and the dorsal face of the digastric muscle.
