下歯槽動脈 - Arteria alveolaris inferior

説明

 The Inferior Alveolar Artery descends with the inferior alveolar nerve to the mandibular foramen on the medial surface of the ramus of the mandible. It runs along the mandibular canal in the substance of the bone, accompanied by the nerve, and opposite the first premolar tooth divides into two branches, incisor and mental.Near its origin the inferior alveolar artery gives off a lingual branch then, enters the foramen, it gives off a mylohyoid branch.The inferior alveolar artery and its incisor branch during their course through the substance of the bone give off a few twigs which are lost in the cancellous tissue, and a series of branches which correspond in number to the roots of the teeth: these enter the minute apertures at the extremities of the roots, and supply the pulp of the teeth.
