Study Notes
Epithelial Tissue Types and Characteristics
- Simple Epithelium: Composed of a single layer of cells, specialized for diffusion, secretion, or absorption.
- Stratified Epithelium: Composed of multiple cell layers, providing protection.
- Squamous Cells: Flattened, plate-like cells.
- Cuboidal Cells: Cube-shaped cells.
- Columnar Cells: Tall, column-shaped cells.
- Simple Squamous: Single layer of flattened cells, facilitating diffusion (e.g., lungs, capillaries).
- Simple Cuboidal: Single layer of cube-shaped cells with a central nucleus, specialized for secretion (e.g., kidneys, gland ducts).
- Simple Columnar: Single layer of tall cells with nuclei, optimized for absorption (e.g., stomach, intestines).
- Stratified Squamous: Multiple layers of flattened cells, providing protection against abrasion (e.g., skin, mouth, vagina).
- Pseudostratified Columnar: Single layer of cells of varying heights, appearing multilayered. Cilia are often present, moving substances (e.g., trachea, windpipe).
- Transitional Epithelium: Specialized cells that change shape in response to stretching, preventing diffusion (e.g., bladder, ureters).
Epithelial Tissue Functions
- Diffusion: Movement of substances across a membrane due to concentration gradients (Simple Squamous).
- Secretion: Release of substances produced by cells (Simple Cuboidal).
- Absorption: Uptake of substances by cells (Simple Columnar).
- Protection: Barrier against abrasion and pathogens (Stratified Squamous).
- Movement of substances: Cilia in pseudostratified columnar tissue move material along surfaces.
- Distensibility/Stretching: Ability to change shape in response to stretching (Transitional).
Epithelial Tissue Locations
- Simple Squamous: Lungs and capillaries.
- Simple Cuboidal: Kidneys and gland ducts.
- Simple Columnar: Stomach and intestines.
- Stratified Squamous: Skin, mouth, and vagina.
- Pseudostratified Columnar: Trachea.
- Transitional: Bladder and ureters.
