What is ECM?
EXTRACELLULAR MATRIX (ECM)
Filler in ECM
Reticular
Single layer
Simple
3 classes of fibers
Collagen
Elastin
Reticular
These are the characteristics of ___________
- Cells arranged in continuous sheet (single or multiple layers)
- Does not have ECM
- Protective covering external and internal surface of the body
Epithelial Tissue
This determines the type of epithelium
Layer and Shape
False stratified
Pseudostratified
Multiple layer
Stratified
It is a shape that can be compare to scales and it is wider than taller, usually found in surface
Squamous
Cube type, they are taller as they are wide
Cuboidal
Column type, taller than they are wide
Columnar
No definite shape and is flexible
Transitional Epithelium
What are the functions of Epithelium?
Protection
Secretion
Absorption
Sensory Reception
Excretion & Filtration
These are the ____________ of Epithelium
- Cover surfaces of body
- Consist entirely of cells
- Has free or apical surface
- Has lateral surface
- Has basal surface
- Does not contain blood vessel
Characteristics
Single layer of flat thin cells and found where diffusion of filtration occurs
Simple Squamous
Deepest part of the body and mostly found in mouth, esophagus, rectum, and vagina
Non-Keratinized Stratified Squamous Epithelium
Found in skin, the outermost layer and contains protein KERATIN
Keratinized Stratified Squamous Epithelium
