Structural Compartments
The three body compartments/cavities consisting of the cranial cavity, thoracic cavity, and abdominopelvic cavity.
Lumen
Interior space of any hollow organ
Intracellular Fluid
Fluid inside of the cell
Extracellular Fluid
Fluid outside of the cell which includes: plasma and interstitial fluid
Interstitial Fluid
This extracellular fluid is the fluid environment that surrounds most of the cells in the body
Plasma
This extracellular fluid is the fluid portion in the blood
Cell membrane
This outer surface of the cell is composed mostly of lipids and embedded proteins
Fluid Mosaic Model
The many compartments of the outer surface of a cell are not static, but rather can move and rearrange their distribution. This concept is called what?
Integral Proteins
There proteins are tightly bound to the embrace and the only way they can be removed is by disrupting the membrane structure with detergents or other harsh methods
Inclusions
These are particles of insoluble materials inside a cell that are sometimes called non-membranous organelles
Cytoplasm
The ______ includes all the material inside the cell membrane except the nucleus
Ribosomes
These are small, dense granules of RNA and protein that manufacture proteins under the direction of the cells DNA
Cytoskeleton
Insoluble protein fibers form the cell's internal support system, also called its_________
Motor Proteins
These proteins can convert stored energy into directed movement
Mitochondria
These organelles have their own genetic material, and are the primary site of aerobic energy of the cell
Endoplasmic Reticulum
This organelle is a network of interconnected membrane tubes with three major functions: Synthesis, storage, and transport of biomolecules
Golgi Apparatus
This organelle receives proteins made in the endoplasmic reticulum and packages them into vesicles
Nucleus
This organelle in the cell contains all the genetic material used to make proteins and control cell processes
Lysosomes
These are small storage vesicles that contain powerful enzymes and act as the digestive system of the cell
Desosomes
These cell to cell anchoring junctions attach to intermediate filaments of the cytoskeleton
Membranes
Compartments are separated by ________
Functions of the Cell Membrane
1) Physical Barrier: separates the internal environment from the external environment
2) Gateway for exchange: Movement of nutrients, wastes, ions, building blocks, and cells products
3) Communication: Receives vital information from other cells
4) Cell S
Lipid Anchored Proteins
These components of the cell membrane are considered "conjugated
Phospholipids
These molecules have a polar and non polar ends as well as hydrophobic heads and hydrophilic tails.
Integral Proteins
These membrane components span the entire width of the bilayer
Polar End
The ______ of a phospholid faces the inside or outside of the cell
Nucleus
Houses the genetic material of the cell
Cytoplasmic Vesicles
Sac-like structures that contain materials synthesized by the cell. They are also filled with molecules for secretion or storage
Storage Vesicles
Carry substances used by the cell
Secretory Vesicles
Carry substances that will be used by the cell
Smooth ER
This is where the synthesis of lipids occur
Rough ER
This is where protein modification occurs
