| Types of cells in respiratory tract |
|
Definition
1-6: In pseudostratified epithelium.
1. Cilia cells (found in trachea, bronchi, regular bronchioles, terminal bronchioles, respiratory bronchioles)
2. Goblet cells (found in trachea, bronchi, fewer in regular bronchioles)
3. Brush cells (found in trachea, bronchi, and regular bronchioles)
4. Small Granular Cells (found in trachea and bronchi, rare in regular bronchioles)
5. Basal cell (in trachea, bronchi and regular bronchioles)
6. Intermediate cell (In trachea, bronchi, and regular bronchioles)
7. Clara cells (In terminal and respiratory bronchioles)
8. Type I Pneumocyte (In alveoli)
9. Type II Pneumocyte (In alveoli) |
