AP Psych Unit 3 Module 9: Biological
Psychology and Neurotransmission

Phrenology - correct answer Made by Franz Gall; studying bumps on the skull could
reveal a person's mental abilities and characteristics. Debunked but paved way for localization of
function



Biological psychology - correct answer Scientific study of links between biological
(genetic, neural, and hormonal) and psychological processes



Biological revelations of the brain - correct answer - Body made of cells

- Nerve cells conduct elec. and send chem msgs across synapses

- Regionalization of function

- Integrate info in diff parts of brain to construct experiences

- Adaptive brain wired by our experience



Nervous system - correct answer - Electrochemical communication system of the
body

————————

Brings info from sense to brain and sends msgs from brain to body for movement



Neuron - correct answer A nerve cell; the basic building block of the nervous
system. Receive info from other neurons, carry info, and pass the info onto the next neuron.

All differ but have the same theme



Cell body/soma - correct answer Cells' life support center that contains nucleus and
helps maintain health



Dendrites - correct answer A neuron's bushy, branching extensions that receive
msgs and conduct impulses toward the cell body

, Axon - correct answer Neuron extension that passes msgs thru its branches to other
neurons or muscles or glands



Axon Hillock - correct answer Connection between soma and axon



Myelin sheath - correct answer A fatty tissue layer segmentally encasing the axons
of some neurons' enables vastly greater transmission speed as neural impulses hop from one node to
the next.

————————

Grows neural efficiency, judgment, and self-control (25). Multiple sclerosis (strength degens,
communications slow with eventual loss)



Nodes of Ranvier - correct answer Tiny space between every myelin sheath where
ions pass in and out



Axon terminals - correct answer Endpoint of a neuron where neurotransmitters are
stored



Action potential - correct answer A brief electrical charge that travels down its axon



How neurons generate electricity from chemical events - correct answer Exchanging
ions



Resting potential - correct answer Fluid outside axon's membrane = + ions

Fluid inside axon's interior = - ions

————————

State of a neuron when it is at rest and capable of doing action potential



Depolarization - correct answer Ions enter the neuron through selectively
permeable axon, making it more susceptible to fire an action potential
