TISSUES Flashcards
Tissue functions as:
- selective barriers
- secretory and protective surfaces
Epithelial Tissue
Tissue composed of cells to cover apical surface, lines hollow organs, and forms glands
Epithelial Tissue
Structure of tissue composed of a:
- apical surface
- lateral surface
- basal surface
Epithelial Tissue
A thin layer anchoring the epithelial cells to underlying connective tissue for cell migration during growth/wound healing
Basement Membrane
Epithelial Tissue classified into 3 layers:
Name/define
- Simple Layer (passage of substance)
- Pseudostratified Layer (not all cells able to reach cell surface, some with cilia and secret goblet cells)
- Stratified Layer (for protection)
Epithelial classified into 3 shapes:
Name/describe
- Squamous (flat and thin)
- Cuboidal (cubed)
- Columnar (tall and wide)
An epithelium gland secretes products into ducts and empty onto the epithelial surface
Exocrine glands
An epithelium gland secretes products into interstitial fluid and diffuse into bloodstream
Endocrine glands
Tissue consisting of extracellular matrix and cells
Connective Tissue
Tissue functions to support, bind, and protect other tissues or organs
Connective Tissue
Extracellular matrix contains 2 types of material:
- Protein Fibres
- Ground Substance
A white, strong protein fibre that resist tensile forces
Collagen Fibres
A yellow, strong and stretchy protein fibre
Elastin Fibres
Thin, fine collagen fibres form branching networks
Reticular Fibres
A gel-like support around a cell exchanging substances between the blood and cell
Ground Substance
