anatomia da artÉria lingual profunda em sus scrofa domestica, linnaeus, 1 758

We studied the arteries of the tongue of Sus scrofa doméstica (Linnaeus, 1 758) from 20 animals whose tongues were slaughtered while fresh and kept cooled (4ºC) for transportation. The blood vessels of 1 5 animals were flowed with water (37ºC), injected with stainedlatex, fixated with phormaldeid and dissected with magnifying glass. We injected 5 tongues with air and acetone PA; later, we injected again with air and at last with vinyl stained acetate. The material was put in water for 24 h and, after this, submerged in sulfuric acid 30% for two weeks to reveal the arterial system mold. The arteries provided dorsal, ventral and collateral branches in the following way: dorsal branches at the tongue root - three branches (50%), four branches (46.6%), five branches (3.4%); arrangements of the following dorsal and ventral branches at the tongue body - one ventral and two dorsal (46.6%), one ventral and three dorsal (23.3%), one ventral and one dorsal (23.3%), one ventral and four dorsal (3.4%) and one ventral branch (3.4%). At the lingual apex, the artery was parallel between antimers, made a medial curve, and reached the counter-lateral artery, establishing anastomoses by inosculation, forming arterial islands from which radial branches to the tip of the tongue were originated.
