| − | ==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 muscle fibres.

| | | | |
| − | A few caudally directed '''horny papillae''' are present on the avian tongue. There is a thick '''stratified squamous epithelium'''. The tongue 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|syrinx species differences]]).
