Phrenology highlighted the presumed function of ... ?
Specific Brain Regions
The person mosst likely to suggest that the shape of a person's skull indicates the estent to which that individual is argumentative and aggressive would be a :
phrenologist
Dr. Wolski does research on the potential relationship between neurotransmitter deficiencies and mood states. Which psycological specialty does Dr. Wolski's research best represent?
Biological Psychology
A biological psychologist would be most interested in the relationship between :
body chemistry and violent behavior
Dendrites are branching extensions of
neurons
the function of dendrites is to :
receive incoming signals from other neurons
An axon is :
the extension of a neuron that carries meassages away from the cell body
The longest part of a motor neuron is likely to be the :
Axon
In transmitting sensory information to the brain, an electrical signal within a signal neuron travels from the :
Dendrites to the cell body to the axon
The speed at which a neural impulse travels is increased when the axon is encased by a(n) :
Myelin Sheath
Neural impulses may travel as rapidly as
200 miles per hour
A brief electrical charge that travels down the axon of a neuron s called the :
Action potential
The depolarization of a neural membrane creates a(n)
Action Potential
An action potential is generated by the movement of
Ions
The resting potential of an axon results from the fact that an axon membrane is :
selectivley permeable
resting potential is to action potential as ____ is to ____
polorization is to depolorization
With regard to the process of the neural transmission, a refractory period refers to a time interval in which :
Positively charged atoms are pumped back outside a neural membrane.
The minimum level of stimulation required to trigger a neural impulse is called the :
Threshold
Increasing excitatory signals above the threshold for neural activation will not affect the intensity of an action potential. This indicates that a neuron's reaction is :
an all-or-none response
A slap on the back is more painful than a pat on the back because the slap triggers :
More frequent neural impulses
Sir Charles Sherringtion observed that impulses took more time to travel a neural pathway than he might have anticipated. His observation provided evidence for the existence of :
Synaptic Gaps
A synapse is a(n)
a junction between a sending neuron and a recieving neuron
The chemical messengers released into the spatial junctions between neurons are called:
neurotransmitters
Neurotransmitter is to ion as ____ is to ___
Molecule is to atom
Neurotransmitters are released from vesicles located in knoblike terminals on the:
Axon
Reuptake refers to the:
Reabosrotion of excess neurotransmitter molecules by a sending neuron
Research on neurotransmitters indicates that :
Neurotransmitters can inhibit neural impulse transmission
Alzheimer's disease is most closely linked to the loss of neurons that produce :
acetylcholine
Epinephrine is to hormone as acetylcholine is to
neurotransmitter
schizophrenia is most closley linked with excess receptor activity for the neurotransmitter :
dopamine
An undersupply of serotonin is most closely linked to:
Depression
Gaba is to glutamate as ___ is to ___
inhibitory neurotransmitter is to excitatory nuerotransmitter
Migraine headaches are most closely linked with an ____ of ____
oversupply of glutamate
Transferring messages froma motor neuron to a leg muscle requires the neurotransmitter known as :
acetylcholine
Botulin poisoning from improperly canned food causes paralysis by blocking the release of :
acetlycholine
Endorphines are :
Neurotransmitters
Opiate drugs occupy the smae receptor sites as :
Endorphins
Jose has just played a long, bruising football game but feels little fatigue or discomfort. His lack of pain is most likely caused by the release of :
endorphins
Hormone is to neurotransmitter as epinephrine is to:
Endorphins
Th body's natural production of endorphins is likely to be ___ by heroin use and ___ by acupuncture
decreased;increased
