Which nerves travel through the infraorbital canal?

Which nerves travel through the infraorbital canal?

• A. MSA and ASA
• B. PSA and IO
• C. ASA and IO
• D. MSA and PSA

Answer: (A)

The infraorbital canal carries branches of the maxillary division of the trigeminal nerve as it travels to the upper teeth. As the infraorbital nerve passes through this canal, it gives off two key dental branches: the middle superior alveolar nerve and the anterior superior alveolar nerve. These nerves course toward the premolars and canines/incisors, respectively, and are the ones associated with traveling through the infraorbital canal. The posterior superior alveolar nerve takes a separate route to the posterior maxilla and does not pass through this canal, which is why it isn’t included here.
