The palatine raphe (also median palatine raphe (2025). 9780323396349, Elsevier. ISBN 9780323396349) is a raphe of the oral cavity. It is a narrow, slight midline ridge extending anteroposteriorly across the palate, from the incisive papilla anteriorly to the palatine uvula posteriorly. Beneath the raphe, the submucosa is absent.
The greater palatine foramen may be palpated on either side about half way between the palatine raphe, and the palatal gingival margin of the 2nd or 3rd upper molar tooth.
The palatine raphe serves as an attachment for multiple muscles: the palatoglossus muscle arises from the posterior portion of the raphe; the levator veli palatini muscle and (the tendon of) the tensor veli palatini muscle insert into the raphe.
