==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.

A few caudally directed '''horny papillae''' are present on the avian tounge. There is a thick '''stratified squamous epithelium'''. The tounge is keratinised and has mucoid glands, although has no [[Tongue - Anatomy & Physiology#Taste Buds|taste buds]]. Lymphatic tissue is spread throughout the '''corium'''.

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