[Sensory nerve endings of the medium and posterior parts of Cebus apella monkey's tongue mucosa].

Sensory nerve endings of tongue mucosa of Cebus apella monkey were studied using the silver impregnation technique (WINKELMANN & SCHIMITT). Subepithelial sensory nerve endings of different forms are present in the medium and posterior parts of tongue mucosa. The nerve fibers have their origin in the deep layers of the tongue and form single and complex sensory nerve endings. The fungiform papillae contain numerous ramified nerve fibers, which constitute a subepithelia network, but the filiform papillae usually possess single free nerve endings disposed longitudinally into the connective tissue.
