Study Notes
Tracheal Structure
- The trachea is formed by 16 to 20 C-shaped pieces of hyaline cartilage connected by dense connective tissue.
Tracheal Lining
- The trachea is lined by respiratory epithelium, which is ciliated pseudostratified columnar in structure.
- The respiratory epithelium consists of various cell types, including: • Goblet cells • Brush cells • Endocrine cells • Surfactant-producing cells (Clara cells) • Serous cells • Basal cells
- The epithelium rests on a basement membrane.
Bronchi Structure
- Bronchi are histologically similar to the trachea.
- They are lined by ciliated, pseudostratified columnar epithelium, also known as respiratory epithelium.
- Goblet cells are interspersed throughout the epithelium.
