Tongue
The tongue in frogs is large, sticky, muscular and protrusible.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.The upper surface has taste buds forming small papillae and mucous glands of which the
secretions cause the tongue to be sticky.
