Ch. 4 Tissues

Question 1

Keratinized stratified squamous epithelium is found in the?

Answer 1

skin

Question 2

What are some characteristics of epithelium tissue?

Answer 2

1. Mostly composed of cells: Epithelial tissue consists of cells with very little extracellular matrix between them
2. Covers body surfaces: Most epithelial tissue covers body surface and forms glands derived developmentally from the body
3. Distinct cell surface: Most epithelial cells have at least one free surface. Where are cells are exposed and do not attach to other cells.
4. Cell and matrix connection: Specialized cell contact bind adjacent epithelial cells together and the extracellular matrix to the basement membrane.
5. Nonvascular: Blood vessels do not penetrate the basement membrane to reach the epithelial. All nutrients and gasses from the blood are transported through diffusion to the epithelium
6. Capable of regeneration- Epithelial tissue has the ability to replaced dangled cells with new epithelial cells.
