coronal suture

connects frontal and parietal bones

ethmoid bone

cranial , unpaired

temporal bone forms part of ________________

cranial floor

frontal bone

cranial unpaired

cora

crow

coron

crown

based on what you now about the maxillary sinus, why would significant impact to maxilla create a more difficult situation for healing than would a fracture to a long bone?

due to the maxillary sinus, there isnt much bone in the wall of maxilla. Long bones are thicker and easier to set. The healing of maxilla is like trying to put an eggshell back together.
