FPC 2 Exam 1 Practice

The main idea is that the neurovascular canals in the maxilla transmit the nerves and blood vessels that supply the teeth and surrounding structures. The posterior superior alveolar canal specifically carries the posterior superior alveolar vessels together with the posterior superior alveolar nerve to the molar region of the maxilla. That’s why the posterior superior alveolar vessels are found in these canals. The other vessels are associated with different maxillary canals: infraorbital vessels with the infraorbital canal, anterior superior alveolar vessels with the anterior superior alveolar nerves in the anterior maxilla, and descending palatine vessels with the greater palatine canal for the palate.
