“…In the rat, however, the first and second branches were usually found as branches of the ascending palatine artery. The origin of this artery was located not only on the external carotid and the lingual but also on the facial as mentioned by Ohtsuka (1979). Greene stated that this artery terminated in three branches between the tympanic bulla and the external pterygoid process.…”

Summary:The whole ramifications of the lingual artery and their distribution features in the rat were investigated by means of the acryl plastic injection method. For convenience, the tongue body was divided into fixed and unfixed (including the lingual apex) portions. The lingual artery arising from the external carotid artery gave rise to the ascending palatine artery and the hyoid branch, and its main stream terminated in the sublingual and the deep lingual arteries.The hyoid branch supplied the lingual radix asymmetrically. The sublingual artery was observed on the mylohyoideus muscle in all 200 examples, although it was always extremely underdeveloped.The deep lingual artery, ramificating into the styloglossal, the geniohyoid and the dorsal lingual branches in the fixed portion, passed forwards between the styloglossus and the genioglossus muscles and terminated in the dorsal branches in the fixed portion formed an arterial network, and one of them in this portion itself turned to the dorsal apical branch, which continued as the dorsal median branch. Vascular communications between the right and left sides within the tongue were interrupted by the presence of the lingual septum in the fixed portion of the lingual body, but in the unfixed portion were maintained by anastomoses between the dorsal and ventral median branches.In short, the deep lingual artery was observed mostly as a unilateral distribution feature in the fixed portion, but was bilateral in the unfixed portion.

“…Greene did not describe this artery. Ohtsuka (1979) stated that the sublingual of the rat did not arise from the lingual but from the facial and was represented as the carnivora type. The present author, however, confirmed that this vessel always arose from the lingual in all the examples observed, although it was not strong.…”

“…In the 18 of 78 cases where the sublingual branches were absent, they were usually compensated for by the in ferior branch of the alveolingual artery, which was well-developed and extended anteriorly beyond the usual location (Figs. 5,6,14), and rarely by the mylohyoid branch. Among the sublingual branches, the posterior one passed forwards, giving off small twigs to the minor sublingual gland, to join with a backward branch of the anterior.…”

“…In cases where one branch was present, it originated opposite the first molar. In cases where two branches were found (Figs,3,6), the posterior one originated opposite the first to second molars, and the anterior one opposite the premolar at an interval of 4-5 mm. In animals where lymph node branches from the sublingual were lacking, it derived directly from the facial artery.…”

Summary.The arterial vasculature in the region of the floor of the mouth was studied in the guinea pig by means of the acryl plastic injection method.1. The arteries observed in the region were the sublingual artery of the facial, the alveolingual of the maxillary and the sublingual branches of the lingual.2. The branches of the sublingual were as follows : (1) the mylohyoid branches to the muscle, (2) the muscular branches to the digastric, mylohyoid and geniohyoid muscles, (3) the submandibular lymph node branches to the nodes, skin and muscles in the submental and submandibular regions, (4) the mandibular transversal branches to the muscle, (5) the alveolar branches to the periodontal tissue of the incisors and adjacent bone, (6) the preincisive branch (the terminal) to the labial gingiva and mucosa of the incisors, the symphysis and the adjacent tissues, and (7) the retroincisive branch (the terminal) to the lingual and lateral gingivae of the incisors, the symphysis and the adjacent tissues.3. The alveolingual artery of the maxillary divided below the third molar into superior and inferior branches.They anastomosed with the sublingual branch of the lingual near the minor sublingual gland to form two arterial arches in the alveolingual area, supplying the lingual gingiva of the molar region, the mylohyoid muscle and the lingual nerve.4. The sublingual branches of the lingual supplied the sublingual papilla, the adjacent mucosa, the originating portion of the geniohyoid and genioglossal muscles and the minor sublingual gland.
