55. •Form ridges on posterior lateral surface of tongue
•Functional and noticeable papillae in the neonate
that are reduced in size as one ages
Serous glands
Dorsal
ducts
Taste buds

56. The superficial cells are dead but retain the nucleus in parakeratinized
epithelium but the nuclei are lost in orthokeratinized epithelium.
The rete pegs are long and slender in keratinized epithelium
Orthokeratinized epithelium Parakeratinized epithelium

Serous glands
(Von Ebner’s)
Dorsal
Serous glands wash substances from taste buds
and secrete lipase, which prevents a hydrophobic
layer from forming over the taste buds
