Plate 10.180 Tongue: Mucous and Serous Glands

Human, Zenker's fluid, phosphotungstic acid hematoxylin stain, 26 x.

Mixed serous and mucous glands (glands of Nuhn*) are found in the anterior two thirds of the inferior surface of the tongue. They are shown here intermixed with striated muscle fibers, collagenous connective tissue, and fat.

Fat cells: Appear empty because their lipid content has been lost in tissue preparation.

Collagenous connective tissue: Surrounds and supports the glands and encompasses muscle fibers to form fascicles.

Mucous glands: Embedded between muscle fascicles. Appear lightly stained.

Mucous gland ducts: Several are seen in this figure. They open primarily on the surface of the tongue.

Serous glands: Scattered among muscle fascicles. The cytoplasm stains more deeply here than in mucous glands.

Striated muscle longitudinal section: Interlacing muscle fibers of the tongue run in three directions: longitudinal, transverse, and vertical. The muscle fibers located between glands are inserted in the dense connective tissue beneath the surface epithelium.

*Nuhn was a nineteenth-century Heidelberg anatomist.
