Epithelium lining of lingual surface of epiglottis is?
ANSWER: (D) Stratified squamous epitheliumREF: Basic Histology by Lange 11th edition Chapter 17 '"The Respiratory System"See APPENDIX-10 below for "SOME IMPORTANT EPITHELIUM LININGS".The epiglottis is a flap valve that covers the laryngeal airway during swallowing. Thus the epithelium facing the oral cavity is oral epithelium, while the epithelium on the surface facing the airway is respiratory.The entire lingual surface and the apical portion of the laryngeal surface are covered with stratified squamous epithelium. Toward the base of the epiglottis on the laryngeal surface, the epithelium undergoes a transition into ciliated pseudostratified columnar epithelium.
