Relating to both the ethmoid bone and the nasal bones, which form the bridge and structure of the nose.
From ethmo- (ethmoid) + nasal (Latin nasus, nose). Anatomical adjective combining structures that work together to form the nasal skeleton.
The ethmonasal region includes the delicate bridge of your nose—this is why a broken nose can affect not just your appearance but also your breathing, since these bones are intimately connected to your nasal passages.
