PSB2000 Test Review 2/1/2013 9:06:00 AM
Differentiate among and give examples of the biological
explanations of behavior:
functional, ontogenetic (dealing with the individual),
biological, evolutionary (evolution of the species),
Discuss why animals are used in research and what limitations
Lecture 2: Genetics
What are genes made of? What do they do? How?
Translated from RNA to DNA
What is meant by dominant and recessive? In what type of
organization will certain traits be expressed? What does sex have
to do with it?
Sex linked recessive: shows up in men more than women
Sex limited: expression is influenced by sex hormones
Differentiate between epigenetics and mutation.
How do you study the influence of genes and behavior?
Knock out mice: mice with certain gene removed.
Lecture 3:Cells of the nervous system: neurons and glia
What functions do the cell organelles perform?
How are the neurons different to and similar to normal body
Shape is different
What functions do the special part of neurons perform?
How does info travel through a neuron? Describe the diff. types of
neurons & how they pass info efferently and afferently.
To the muscles/ motor neurons = efferent (on the spinal
Sensory neurons = afferent What are the functions of the types of glial cells? What‟s the
function of the blood brain barrier?
To keep diseases out of the brain
Lecture 4: The resing membrane potential (7 questions)
What does it mean that a neuron‟s membrane is polarized? Diff.
b/t depolarization and hyperpolarization.
Which was to the ions on the inside and outside of the cell „want‟
to move and why? Why can/can‟t they?
More sodium outside the cell, and more potassium inside.
So based on this sodium wants to go in, and potassium
Based on charge both want to go in.
Sodium can‟t go into the cell because the membran
