[Lingual innervation in the buffalo].

The lingual and papillary mucosa innervation has been studied in the buffalo by histochemical and immunohistochemical techniques and by gold impregnation method of Ruffini. In lingual mucosa the presence of ganglionic structures has been noticed in which there are numerous cellular bodies and bundles of fibres variously directed. Particularly in the vallate papillae, the papillary stroma contains myelinic and unmyelinated fibres and terminal nerve corpuscles. Along stromal myelinic fibres the presence of the proteins S-100 and NF has been demonstrated.
