Which nerve innervates the mucous membrane of the soft palate?

Explanation:
The soft palate mucosa is supplied by the lesser palatine nerves, which branch from the descending palatine nerve (a branch of V2 via the pterygopalatine ganglion). Among these lesser palatine nerves, the middle palatine nerve serves the central region of the soft palate mucosa, making it the correct choice for innervation of that area. The greater palatine nerve mainly supplies the hard palate mucosa and gingiva, while the other lesser palatine branches (anterior and posterior) cover different regions, but the middle palatine nerve is the one most closely associated with the soft palate’s mucous membrane.
