Study Notes
Epithelial Tissue Classification
- Epithelial tissue is categorized based on cell shape and layer number.
- There are different types of epithelial tissue, including simple and stratified classifications.
Simple vs. Stratified
- One layer of cells is referred to as simple epithelium.
- Multiple layers of cells categorize epithelial tissue as stratified epithelium.
Cell Shapes in Epithelial Tissue
- Squamous cells are characterized by their thin, flat, and scaly appearance, ideal for processes like diffusion and filtration.
- Cuboidal cells are typically cube-shaped, can be rounded or square, and are involved in secretion and absorption.
- Columnar cells are taller than they are wide, often found in areas requiring significant absorption or secretion.
Pseudostratified Epithelium
- Pseudostratified cells appear multilayered due to uneven distribution of their nuclei within the cell layers.
