  • The floor is formed anteriorly by the palatine processes of the maxilla, and posteriorly by the palatine bone.
  • The lateral wall is formed from the maxilla, and the three conchae (superior and middle nasal conchae are both part of the ethmoid bone, while the inferior nasal concha is a separate bone).
