1. SIMPLE EPITHELIUM

2. Four types of tissues:
1. EPITHELIUM TISSUE - More cells, small amount of extracellular substance - Lining the surface of the body, lumen of body cavities and can be found in glands (secretion) 2. MUSCLE TISSUE 3. CONNECTIVE TISSUE 4. NERVOUS TISSUE

3. Types of epithelium: Lining epithelium Glandular epithelium
- simple
- pseudostratified
- transitional
- stratified
Glandular epithelium
Neuroepithelium

4. SIMPLE SQUAMOUS EPITHELIUM
Function: lining and protection
Localization: serous membranes, renal corpuscle, blood vessels, cornea,..

5. SIMPLE SQUAMOUS EPITHELIUM
corpusculum renis
Nuclei of squamous cells

6. SIMPLE SQUAMOUS EPITHELIUM -
Nuclei of the squamous cells

7. SIMPLE CUBOIDAL EPITHELIUM
epithelial cell
nucleus
basal lamina
Function: lining the surfaces, secretion
Localization: ovaries, renal tubules,
thyroid gland,...

8. SIMPLE CUBOIDAL EPITHELIUM
nucleus of cuboidal cell
basal lamina

9. SIMPLE COLUMNAR EPITHELIUM
Function: lining, absorption
Localization: collecting ducts in kidney,
gallbladder,...

10. SIMPLE COLUMNAR EPITHELIUM
basal lamina
apical part of columnar cell
simple squamous epithelium
nucleus of columnar cell

11. SIMPLE COLUMNAR EPITHELIUM
