Tongue
The tongue in frogs is large, sticky, muscular and protrusible. It is found at the base of the
mouth cavity. The anterior end of it is attached to the inner border of the lower jaw while the
posterior end is bifid and free.
The upper surface has taste buds forming small papillae and mucous glands of which the
secretions cause the tongue to be sticky. Digestive enzymes are neither produced by the
mucous glands nor the taste buds.
The tongue can be protruded and suddenly retracted to engulf and capture insects. It is said
that the throwing out of the tongue is caused by a sudden flow of the squeezed lymph
contained in the lymph sac to the other as a result of muscular contraction. However,
swallowing is attained by elevating the buccal cavity’s floor wherein flat, hyoid cartilage is
implanted.
