The innervation pattern of the hard palate of the wistar albino rat

A modified Sihler technique was used to investigate the innervation of the hard palate. Nervi palatinin majores and minores showed slight individual variations. The antemolar area was innervated by a very fine diffuse network. In the intermolar region most of the terminal branches ended within the papillae which are on top of the rugae. The lateral intermolar region had a more dense innervation than the medial region. A diagram of the areas innervated by the different palatal nerves is presented.
