==Structure and Function==

==Structure and Function==

The avian tongue is narrow, pointed and contains little intrinsic muscle. The '''enteroglossal bone''' is present consisting of bone and cartilage with medullary spaces containing red marrow. It is supported by the lingual process of the '''[[Hyoid Apparatus - Anatomy & Physiology|hyoid bone]]''' and rudimentary lingual muscles. It contains striated muslce fibres.

*Parrots use their muscular tongue to lap water

'''Parrots''' use their muscular tongue to lap water and to produce human sounds (see [[Syrinx - Anatomy & Physiology#Species Differences|here]]).
