Of the Following Structures,which is the MOST Susceptible to Trauma

Question

Of the following structures,which is the MOST susceptible to trauma?
A) Hard palate
B) Buccal mucosa
C) Floor of the mouth
D) Dorsal surface of the tongue
E) Attached gingiva

Accepted Answer

Although any oral tissue may be traumatized,the tissue in the floor of the mouth is one of the thinnest and thus very conducive to trauma.The hard palate and the attached gingiva have a more protective,fibrous nature.The dorsal (top)tongue and the buccal mucosa also have more protective features than does the mucosal lining on the floor of the mouth.Not listed as a selection,the ventral (lower)surface of the tongue is quite vulnerable to trauma.
