Small foramina in the lateral wall
Other routes by which vessels and nerves get into and out of the nasal cavity include the nares and small foramina in the lateral wall:
Internal nasal branches of the infra-orbital nerve of the maxillary nerve [V2] and alar branches of the nasal artery from the facial artery loop around the margin of the naris to gain entry to the lateral wall of the nasal cavity from the face.
