UPDATED ACTUAL Questions and
CORRECT Answers
Origins of Medical science - CORRECT ANSWER - 1.) Started with superstition and magic
2.) Originated in Greek & Latin terminology
Scientific Method - CORRECT ANSWER - "Investigating the Natural World"
Testing a Hypothesis = - CORRECT ANSWER - 1.) Rejecting or Accepting the hypothesis
2.) Based on results of experiment and observations
Anatomy + Physiology = ? - CORRECT ANSWER - How the body maintains life
Anatomy - CORRECT ANSWER - "cutting up"
1. structures of the body
2. Forms/ organization
Physiology - CORRECT ANSWER - "relationship to nature"
1. functions of the body
2. What do they do and how?
Gene Expression Profiling - CORRECT ANSWER - Reveals commonalities among pairs of
diseases that had not been suspected based on whole-body-level observations
Chemical Organization - CORRECT ANSWER - 1.Atoms
2. Molecules
,Subatomic Particles - CORRECT ANSWER - Make up atoms
Molecules - CORRECT ANSWER - Where atoms join together
Macromolecules - CORRECT ANSWER - Small molecules join together to make larger
molecules
Human Organism Organization smallest-largest - CORRECT ANSWER - 1. Subatomc
particles
2. atoms
3. molecules
4. macromolecules
5. organelles
6. cells
7. tissues
8. organs
9. organ systems
10. organisms
Cells - CORRECT ANSWER - basic unit
Organelles - CORRECT ANSWER - carry on specific activities
e. proteins, carbohydrates, lipids, nucleic acids
tissues - CORRECT ANSWER - layers/masses of cells with special functions
Organs - CORRECT ANSWER - groups of tissues with specific functions
,organs systems - CORRECT ANSWER - groups of organs that function close together
organisms - CORRECT ANSWER - interacting organ systems
Internal environment - CORRECT ANSWER - environment within the body in which the
cells live
Cell membrane - CORRECT ANSWER - interior and exterior cell membranes
Interior cell membrane - CORRECT ANSWER - intracellular fluid
exterior cell membrane - CORRECT ANSWER - extracellular fluid
homeostasis - CORRECT ANSWER - the maintenance of a relatively constant internal
environment
Interdependency of cells - CORRECT ANSWER - -cells depend on one another
-if some cells arent able to function, other cells and the entire organism may suffer
-structure and function are interrelated
Gradients & Permeability - CORRECT ANSWER - down a gradient (High to Low)
high pressure to low pressure
high concentration to low concentration
Diffusion - CORRECT ANSWER - high concentration to low concentration (concentration
gradient)
, membrane permeability - CORRECT ANSWER - what is allowed in to the membrane or not
Permeant - CORRECT ANSWER - substance can pass through
Cellular differentiation - CORRECT ANSWER - cells become specialized
-different cell types (muscle/nerve) access information encoded in different genes to make
specific proteins
-proteins that cells make determine the function
Cell membrane mechanisms - CORRECT ANSWER - -determines which substances enter a
cell and which cannot
-allow cells to respond to certain signals
Cell to cell communication - CORRECT ANSWER - membrane receptors / feedback loops
Feedback loops - CORRECT ANSWER - -negative or positive
-cells signal each other when the internal environment has been compromised so adjustments can
be made to keep homeostasis
-when adjustments have been made, they also signal to show the adjustments are no longer
needed.
Homeostatic Mechanisms = - CORRECT ANSWER - feedback loops
-receptors
-control center
-effectors
Balance within the body - CORRECT ANSWER - must replace substances that are lost and
eliminate substances that are no longer needed or in excess
