1 The superior gluteal nerve and the nerve to quadratus femoris/inferior gemellus share the same nerve roots (L4, L5 and S1).  Similarly, the inferior gluteal nerve and the nerve to obturator internus/superior gemellus also share the same nerve roots (L5, S1 and S2).
In the maxilla, the inferior wall of the infraorbital canal may be incomplete, and hence the infraorbital nerve is in contact with the mucosa of the maxillary sinus. In about 5% of skulls, the infraorbital groove is present as a canal. Two or more infraorbital foramina have been reported.
