Rami nasales posteriores inferiores nervi palatini majoris
- Related terms: Inferior posterior nasal branches; Posterior inferior nasal nerves
Definition
The inferior posterior nasal branches of greater palatine nerve originate from the greater palatine nerve during its descent through the greater palatine canal, inside the maxilla. The greater palatine nerve, as you may know, is a branch of the pterygopalatine ganglion.
Following their origin, the inferior posterior nasal branches of greater palatine nerve pass medially through small foramina in the perpendicular plate of palatine bone to innervate the mucosa, glands of the lateral nasal wall in the region where inferior concha and middle and inferior meatuses are situated.
