Respiratory Trachea - Glands
Mucosa - formed by epithelium and underlying lamina propria.
- respiratory epithelium - (pseudostratified columnar and ciliated) ciliated cells, goblet cells, brush cells, endocrine cells, surfactant-producing cells (Clara cells), serous cells, basal cells, basement membrane.
- lamina propria - loose connective tissue, many elastic fibres
Submucosa - connective tissue and submucosal glands
Submucosal Glands
(muco-serous) serous (dark) and mucous (light) parts have different staining appearance.
- Mucous secretions - "slimy" (high viscosity) mucous acini cells appear "foamy" or "frothy" and poorly stained (light). nuclei dark and smaller than serous.
- Serous secretions - "watery" (low viscosity) serous acini cell apical cytoplasm is usually well-stained (dark). nuclei round to ovoid located in cell basal cytoplasm.
Cartilage
- perichondrium - surface of cartilage.
- tracheal cartilage - hyaline cartilage, 16 to 20 C-shaped cartilages.
- trachealis muscle - (smooth muscle) Not visible in this section, together with connective tissue fibres, join ends of the cartilages together.
