Tonsils & Adenoids (Lymphoid Tissue) of the Pharynx
Pharynx Histology – Epithelial Lining of the Pharynx
Epithelial Lining of the Pharynx (introduction to pharynx histology)
- The surface of the nasopharynx is covered by the same pseudostratified columnar epithelium that is found in the nasal cavity.
- Goblet cells in the epithelium secrete mucus, which further cleans, warms, and moistens inhaled air before it moves deeper into the respiratory tract.
- The other two regions of the pharynx, the oropharynx and laryngopharynx, are lined by nonkeratinizing stratified squamous epithelium.
- These areas also form part of the digestive tract. When food is swallowed, the multiple cell layers in the stratified epithelium help protect the underlying tissues from damage caused by food moving through the passageway.
