The document discusses the different types of epithelial tissues, including squamous, cuboidal, columnar, and pseudostratified epithelia. It describes the structure, function, location, and adaptations of each type. The key types discussed are simple squamous, stratified squamous, simple cuboidal, stratified cuboidal, simple columnar, pseudostratified columnar epithelia. The document provides detailed information on the histology and characteristics of each epithelial tissue.

9. Squamous Epithelia:Structure Simple Squamous Epitheliaconsist of a single layer of flattened cells and it has a nucleus. It’s shape is rather like crazy paving. Stratified Squamous Epithelia has many layers of flattened cells.* Nafly Hussain*

10. Squamous Epithelia: FunctionSimple Squamous EpitheliaIt protects line passageways cavity and cover the pleura, pericardium and peritoneum.Stratified Squamous EpitheliaThis epithelium protects underlying layer and repair itself rapidly if damaged . Outer layer of the cell may be keratinized on dry surface such as skin. * Nafly Hussain*

21. Cuboidal Epithelium* Nafly Hussain*

22. Structure of cuboidal epitheliaCharacteristics : Roughly square in shape.

23. Each cell has a spherical nucleus in the centre.

24. Cells lie on basement membrane.

25. Tightly packed with little or no-inter cellular substance.* Nafly Hussain*
