Cards

Term
Plasma Membrane
Definition
Keeps the cell in a contained environment. Interacts with the environment through its phospholipid bilayer.
Term
membrane proteins
Definition
Partially or completely imbedded in the plasma membrane. They have three functions:

1. Receptors
2. Provide Structure for the Membrane
3. Intercellular Joiners
Term
Microvilli
Definition
Increase the surface area of the cell. Allows for more absorption and secretion.
Term
Membrane Junctions
Definition
1. Tight Junctions
2. Desmosomes
3. Gap Junctions
Term
Tight Junctions
Definition
Made of interlocking proteins, forming a water-tight seal.
Term
Desmosomes
Definition
Anchor one cell to another. Allows for movement of two cells without separation.
Term
Gap Junctions
Definition
Used to transport ions and other particles from one cell to another via CONNEXONS.
Term
Cytoplasm
Definition
Cellular material between the plasma membrane and the nucleus.
Term
Cytosol
Definition
viscous fluid high in K+ ions.
Term
Cytoskeleton
Definition
Supports the cell shape
Term
Three types of Cytoskeleton fillaments
Definition
1. Microtubules
2. Microfillaments
3. Intermediate Fillaments
Term
Microtubles
Definition
Hollow tubes for flexibility
Term
Microfillaments
Definition
Made of small, spherical chains
Term
Intermediate Fillaments
Definition
Made of steel-like bands
Term
Extracellular body fluids
Definition
High in NA+. Dissolves particles. Keeps cells in an aqueous environment:

1. Blood Plasma
2. Cerebro-spinal fluid
3. Interstitial Fluid
Term
Extracellular Matrix
Definition
made of cells, protein fibers, interstitial fluid, etc.
