Ans:A.)Infraorbital poion of Maxillary nerve.The middle superior alveolar nerve is a nerve that drops from the infraorbital poion of the maxillary nerve to supply the sinus mucosa, the roots of the maxillary premolars, and the mesiobuccal root of the first maxillary molar.Branches of Maxillary NerveIts branches may be divided into four groups, depending upon where they branch off: in the cranium, in the pterygopalatine fossa, in the infraorbital canal, or on the face.In the craniumMiddle meningeal nerve in the meningesFrom the pterygopalatine fossaZygomatic nerve (zygomaticotemporal nerve, zygomaticofacial nerve), through the Zygomatic foramenNasopalatine nerve, through the sphenopalatine foramenPosterior superior alveolar nerveGreater and lesser palatine nervesPharyngeal nerveIn the infraorbital canalMiddle superior alveolar nerveAnterior superior alveolar nerveInfraorbital nerveOn the faceInferior palpebral nerveSuperior labial nerve
