This investigation was carried out on 36 larynges of adult male and female dogs (12) goats (12) and donkeys (12). The heads were injected with Gum milk "latex" or with 1:1 solution of indian ink and bovine serum. The present study revealed that the larynx receives its main arterial blood supply from A. laryngea cranialis, R. laryngeus caudalis, R. cricothyroideus and R. perihyoideus, in addition to the A. pharyngea ascendens and the R. thyrohyoideus in the donkey. The origin, course, mode of branching and anastomosis of the laryngeal arteries were studied. The present investigation showed that all the arteries supplying the larynges in the examined species are anastomosed with each other forming unique network.
