Stratified squamous epithelium |
several layers of cells/ apical cells are flat/ serves to protect underlying tissues from abrasion and friction/ location: oral cavity, esophagus, anal canal, vagina/ basal cells undergo mitosis/ oldest cells at superficial layer |
|
|
Pseudostratified columnar epithelium |
one cell layer thick / cells are different height with nuclei at different level/ pseudostratified ciliated columnar (PSCC) with goblet cells/ Location: trachea, bronchi, nasal cavity |
|
