Auscultation Right Ans - Listening with a stethoscope
Percussion Right Ans - taking hands and beating over certain parts of body
Medical Imaging Right Ans - methods of viewing the inside of the body
without surgery, i.e. radiology

Histopathology Right Ans - microscopic examination of tissues for signs of
disease
Cytology Right Ans - study of structure and function of cells
Ultrastructure Right Ans - fine detail, down to the molecular level, revealed
by the electron microscope
Subdisciplines of Physiology Right Ans - neurophysiology, endocrinology,
pathophysiology

Endocrinology Right Ans - study of hormones
Pathophysiology Right Ans - mechanisms of disease
Hippocrates Right Ans - Father of medicine
,Scientific Fact Right Ans - information that can be independently verified
Law of Nature Right Ans - a generalization about the predictable ways in
which matter and energy behave
Theory Right Ans - explanatory statement or set of statements derived
from facts, laws and confirmed hypotheses
Bipedalism Right Ans - the ability to walk upright on two legs
The Hierarchy of Complexity Right Ans - Organ system-organs-tissues-
cells-organelles-molecules-atoms
situs invertus Right Ans - heart is on the opposite side
Organization Right Ans - living things exhibit a higher level of organization
than nonliving things
Cellular Composition Right Ans - living matter is always

Positive Feedback Right Ans - Self-amplifying cycle where the feedback
loop is repeated. Normal way of producing rapid changes. Can sometimes be
dangerous. ex. childbirth
Gradient Right Ans - a difference in chemical concentration, charge,
temperature, or pressure between two points. Chemicals flow down

Heat flows down thermal gradients.
CT Scan Right Ans - computed tomography scan
MRI Right Ans - magnetic resonance imaging
PET scan Right Ans - a visual display of brain activity that detects where a
radioactive form of glucose goes while the brain performs a given task
