Anterior superior alveolar nerve

From Wikipedia, the free encyclopedia

Nerve: Anterior superior alveolar nerve
Distribution of the maxillary and mandibular nerves, and the submaxillary ganglion.
Alveolar branches of superior maxillary nerve and sphenopalatine ganglion.
Latin	rami alveolares superiores anteriores nervi maxillaris, ramus alveolaris superior anteriores
Gray's	subject #200 891
Innervates	dental alveolus

The anterior superior alveolar branch (anterior superior dental branch), of considerable size, is given off from the maxillary nerve just before its exit from the infraorbital foramen; it descends in a canal in the anterior wall of the maxillary sinus, and divides into branches which supply the incisor and canine teeth.

It communicates with the middle superior alveolar branch, and gives off a nasal branch, which passes through a minute canal in the lateral wall of the inferior meatus, and supplies the mucous membrane of the anterior part of the inferior meatus and the floor of the nasal cavity, communicating with the nasal branches from the sphenopalatine ganglion.
