Histology of Respiratory system: Trachea

TRACHEA

Histology of Trachea


  • Epithelum
    – respiratory epithelium (pseudo stratified columnar epithelium with goblet cells).
  • Lamina propria – gradual decrease in thickness & increase in number of elastic fibres.
  • Glands – mucous & serous glands.
  • Skeletal connective tissue – C – shaped hyaline cartilage rings.
  • Muscle – Smooth muscle named trachealis muscle.
