The mixture of short cells and tall cells gives this tissue its falsely stratified look, hence the name

pseudostratified.

Stratified squamous epithelium-In the esophagus, the cells near the basement membrane almost appear cuboidal, but as they approach the lumen they begin to flatten out to a squamousal

shape.

Transitional Epithelium Can be found in the urinary bladder and is marked for its circular

oblong shape.

Dense Connective Tissue

Notice the wavy pink collagen fibers and the darker stained fibroblast cells in rows.
