Tip: Dark band along apical edge= microvilli (increase surface area for absorption)
pseudostratified columnar epithelium
Tip: All cells reach to basement layer, but not all reach apical layer. Nuclei @ varying distances from apical border. Falsley stratified. Indentations are called goblet cells, and they secrete mucous into lumen (open area). Notice banding--this is the microvilli that is found in columnar epithelial cells.
keratinized stratified squamous epithelium
Tip: Can tell it is keratinized because of distinct layers. There are 5 OBVIOUS layers. Covers outer surfaces of body-- i.e. skin.
Keratinized stratified squamous epithelium
a) corneum
b) lucidum
c) granulosum
d) spinosum
e) basal
Keratinized Stratified Squamous Epithelium
Transitional Epithelium
Tip: The circles are on the binucleated cells, which are characteristic of transitional epithelium. The test pointer will likely be right on a binucleated cells.
Loose connective tissue
Tissue: Distinctive purple dots with fibers going in all different directions
