Notes:
Macroscopic and neurohistological observations of the tongues of the pigmy and common marmosets are described. On the dorsum, there are three circumvallate papillae arranged in an inverted V-shape. Through the magnifying glass the foliate papillae with a few clefts are found anterior to the attachment of the glossopalatine fold. The fungiform papillae can be seen with a lens. The vallate papillae are supplied with abundant nerves. The taste buds are located only in the lateral non-cornified wall of the papilla, closely associated with the subgemmal nerve plexus. The lingual glands of the serous type are present deep in the muscle of this region. The ganglion cells composing the ganglion are located inside and below the papilla. The foliate papillae consist of a few furrows with many taste buds and are supplied with abundant nerves and a few ganglion cells. The serous glands are not plentiful. Infiltration of the lymphoid cells in the foliate papilla region should be regarded as the lingual follicle of the primitive type. The fungiform papillae are supplied with abundant nerve fibers which terminate free and are furnished with many taste buds having an embryonic appearance. The papillae are comparable to those of the human fetal or newborn tongue. The “sublingua” is a rudimentary structure having neither sensory nerves nor taste buds. The ganglion cells lying on the nerve fiber bundles in the apical region probably are cells migrating from the submandibular ganglion. No apical glands of Nuhn are present.
