Transcript of Goblet Cells nucleus. When we look at a cross section of the trachea we can see two tissues as well....
Goblet Cells
nucleus
Pseudostratified ciliated columnar epithelium
Hyaline Cartlilage
lumenGoblet cells
cilia
The mixture of short cells and tall cells gives this tissue its falsely stratified look, hence the name
pseudostratified.
Pseudostratified Ciliated Columnar Epithelium
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.
Lumen
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.
Loose Connective Tissue (Areolar)
Elastic Fiber
FibroblastsThe pink background comes from
many wider collagen fibers.
