Lecture 1: Epithelial Tissue
Page 1:
- Histology is made of units
Page 5:
- A group of similar cells performing a similar function (basic definition for tissue)
Page 6:
- Understand that the epithelial tissue is a classification only
Page 7:
- (The function is more enormous than this)
- Protection from abrasions and injury (the elements)
Page 8:
- Zonulae adherents: adherens junctions
Page 11:
- Abrasion: stratified squamous
- Absorption: simple columnar
- The top layer of cells defines the classification for a stratified layer
- always look for the lumen
Page 13:

- Look for them at the lumen to orient yourself
Page 14:
- …peiadial aities mesothelium)
Page 15:
- Nuclei of endothelial cells (simple squamous)
Page 16:
- Not viewing perpendicular to the BM - can't be sure it's simple squamous
- Looking at it perpendicular if looking at the BM or the longitudinal section of a tube

Page 17:
- *When looking through microscope, after finding the lumen, first look for division points, then
classify the epithelium, then classify the connective tissue
- The small layer of smooth muscle, the muscularis mucosa--vibration to spread food around for
absorption

- …etall plaed uleus (sometimes nucleus shifts down as an artefact of cutting)
