Lingual Salivary Glands
In this cross-section through the tongue of a newborn infant, can you identify fungiform (A) and filiform (B) papillae of its dorsal surface? On either side of the midline in the lower half of the tongue are two masses of bracketed glandular tissue. These are the anterior lingual glands (C). They secrete onto the ventral surface of the tongue. Look carefully at the intrinsic musculature of the tongue. Can you identify bundles of skeletal muscle fibers (D) extending at right angles to one another?
