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
  • 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)
