What is Anatomy?
The study of the structure of an organism and its parts.
What is Physiology?
The study of the body functions in a living organism
What is Pathophysiology?
The study of body functions of a living organism in an abnormal state
What are the five body cavities?
What is the coronal (frontal) plane?
A vertical plane running from side to side; divides the body or any of its parts into anterior and posterior portions.
What is the sagittal (lateral) plane?
A vertical plane running from front to back; divides the body or any of its parts into right and left sides.
What is the transverse (axial) plane?
A horizontal plane; divides the body or any of its parts into upper and lower parts
What is diffusion?
The movement of solutes (particles) from an area of high concentration to an area of low concentration
HIGH TO LOW
What is osmosis?
The movement of a solvent (usually water) from an area of low solute concentration to an area of high solute concentration
LOW TO HIGH
What is facilitated diffusion?
The process in which a carrier molecule moves substances in or out of the cell; energy is not required
NO ENERGY NEEDED
What is active transport?
The movement of a substance against their concentration or gradient; requires energy
NEED ENERGY TO MOVE
What is anabolism?
Building phase of metabolism, where smaller molecules are converted to larger molecules
SMALL TO BIG
What is catabolism?
The break-down phase of metabolism, in which larger molecules are converted to smaller molecules
BIG TO SMALL
What does cellular respiration create?
Energy in the form of adenosine triphosphate (ATP)
What are the four lobes of the brain called?
Frontal (in the front)
Parietal (behind frontal)
Occipital (in the back)
Temporal (on the sides under parietal)
What four things does the frontal lobe control?
Voluntary motor action
What four things does the parietal lobe control?
What does the occipital lobe control?

What two things does the diencephalon contain?
What three things does the thalamus do?
Processes sensory input
General body movements
What two things does the hypothalamus do?
Regulates body temperature, respiration, and heartbeat
Directs hormone secretions of the pituitary gland
What three things does the brainstem consist of?
What two things does the brain stem do?
Controls functions necessary for life
Plays a roll in consciousness
