Introduction
The size and structure of the avian tongue varies between species. It is related to functional requirements.
Structure and Function

- The enteroglossal bone is present consisting of bone and cartilage with medullary spaces containing red marrow
- Supported by the lingual process of the hyoid bone
- Rudimentary lingual muscles
- Striated muslce fibres
Histology
- A few caudally directed horny papillae are present
- Thick stratified squamous epithelium
- Keratinised
- Mucoid glands
- No taste buds
- Lymphatic tissue spread throughout the corium
