3 Main Cell Components
Definition
Membrane, Nucleus and Cytoplasm
Term
Organelles
Definition
Parts of a living cell
Term
Plasma Membrane - Description
Definition
Outer layer of the cell, composed of lipids and proteins.
Term
Plasma Membrane - Function
Definition
Enclose the cell contents & regulate what enters & leaves the cell; selectively permeable.
Term
Microvilli - Description
Definition
Short extensions of the cell membrane.
Term
Microvilli - Function
Definition
Absorb materials into the cell.
Term
Nucleus - Description
Definition
Large organelle near the center of the cell, composed of DNA and proteins. "Control center of the cell."
Term
Nucleus - Function
Definition
Contains all the chromosomes (hereditary units that direct all cellular activities).
Term
Centrioles - Description
Definition
Rod-shaped bodies near the nucleus.
Term
Centrioles - Function
Definition
Help separate the chromosomes during cell division.
Term
Nucleolus - Description
Definition
Small body in the nucleus, composed of RNA, DNA and protein.
Term
Nucleolus - Function
Definition
Makes ribosomes.
Term
Cytoplasm - Description
Definition
Suspension that fills up the cell from the nuclear to the plasma membrane.
Term
Cytoplasm - Function
Definition
Site of many cellular activities; consists of cytosol and organelles.
Term
Cytosol - Description
Definition
The fluid portion of cytoplasm.
Term
Cytosol - Function
Definition
Surrounds the organelles.
Term
Endoplasmic Reticulum - Description
Definition
Network of membranes within the cytoplasm. Rough contains ribosomes, smooth does not.
Term
Endoplasmic Reticulum - Function
Definition
Rough sorts proteins and forms them into complex compounds; smooth is involved with lipid synthesis. "Transports proteins."
Term
Ribosomes - Description
Definition
Small bodies composed of RNA and protein, free within the cytoplasm or attached to the Endoplasmic Reticulum.
Term
Ribosomes - Function
Definition
Manufacture proteins.
Term
Mitochondria - Description
Definition
Large organelles with folded membranes inside.
Term
Mitochondria - Function
Definition
Convert energy from nutrients into ATP. "The powerhouse of the cell."
Term
Golgi Apparatus - Description
Definition
Layers of membranes.
Term
Golgi Apparatus - Function
Definition
Makes compounds containing proteins, and sorts them for transport within or out the cell.
Term
Lysosomes - Description
Definition
Small sacs of digestive enzymes.
Term
Lysosomes - Function
Definition
Digests substances within the cell. "Waste management."
Term
Peroxisomes - Description
Definition
Membrane-enclosed organelles containing enzymes
Term
Peroxisomes - Function
Definition
Break down harmful substances.
Term
Vesicles - Description
Definition
Small membrane-bound sacs in the cytoplam.
Term
Vesicles - Function
Definition
Store materials and move them in and out of the cell in bulk.
Term
Passive Transport
Definition
Movement through the plasma membrane that does not require energy output from the cell.
Term
Diffusion
Definition
Passive; the movement of particles from areas of high to low concentration
Term
Osmosis
Definition
Passive; the movement of water (H2O) from high to low concentration.
Term
Filtration
Definition
Passive; water and dissolved minerals pass through the membrane by the application of mechanical force on one side.
Term
Active Transport
Definition
Movement through the plasma membrane that requires energy and transporters; movement in the opposite direction it would normally flow by diffusion.
Term
Endocytosis
Definition
Active; bring something into the cell.
Term
Phagocytosis
Definition
Active, endocytosis; cell eats what came in.
Term
Pinocytosis
Definition
Active, endocytosis; cell drinks what came in.
Term
Exocytosis
Definition
Active; material is pushed out of the cell.
Term
Indicated (massage)
Definition
Massage therapy can help a particular condition; this is a green light for massage.
Term
Contraindicated (massage)
Definition
Massage therapy may be harmful; this is a red light for massage. May be local (avoid the area) or systemic (avoid massage altogether).
Term
Precautionary (massage)
Definition
Modify or eliminate a massage or technique to be safe; this is a yellow light for massage.
Term
Beneficial (massage)
Definition
Massage therapy may help for overall well being, but won't have an effect on an existing condition.
Term
Contact
Definition
Touch of any kind
Term
No Contact
Definition
A directive - absolutely no touch on that area.
Term
Pressure
Definition
The force applied in techniques
Term
Light Pressure
Definition
Displaces the skin only.
Term
Medium Pressure
Definition
Displaces the fat and muscle tissues.
Term
Critical Thinking
Definition
A method that takes you through the process of screening for medical conditions, applying basic principles of physiology to determine if massage could adversely affect the condition, and making safe choices.
