Introduction
The size and structure of the avian tongue varies between species. It is related to functional requirements.
Structure and Function
- Narrow
- Pointed
- Contains little intrinsic muscle
- 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
Species Differences
- Parrots use their muscular tongue to lap water
- Parrots use their muscular tongue to produce human sounds (see here)
