Palatine nerves
Encyclopedia
The palatine nerves are distributed to the roof of the mouth
, soft palate
, tonsil
, and lining membrane of the nasal cavity
.
Most of their fibers are derived from the sphenopalatine branches of the maxillary nerve.
In older texts, they are usually categorized as three in number: anterior, middle, and posterior. (In newer texts, and in Terminologia anatomica
, they are broken down into "greater palatine nerve
" and "lesser palatine nerve
".)
