Phrenology is an old belief that bumps on the skull somehow correspond to brain regions that are
responsible for specific behavioral capacities correct answers TRUE
The neural cell nucleus carries genetic instructions encoded in DNA, just like other cells in the
body correct answers TRUE
In terms of the components of a neuron, dendrites are found in the Output Zone correct answers
FALSE
Sensory neurons carry neural messages from peripheral sense organs to the spinal chord and
brain correct answers TRUE
Individual neural cell bodies somehow store sensory information brought in from peripheral
nerves correct answers FALSE
A unipolar neuron has its cell body directly in line with its dendritric and axonal branches correct
answers FALSE
A multipolar neuron has a single dendritic branch correct answers FALSE
Glial cells connect sensory neurons to central neurons correct answers FALSE
The input zone is where axon terminals are found correct answers FALSE
The elaborate branching of dendrites is called arborization correct answers TRUE
There is no space between the pre-synaptic and postsynaptic elements correct answers FALSE
There are usually many axons per neuron correct answers FALSE
The part of the neural cell body that integrates information from all the synapses and initiates
axon impulses is called: correct answers AXON HILLOCK
Oligodendrocytes produce myelin correct answers TRUE
A neuron type that transmits motor messages is a motor neuron correct answers TRUE
What is the range in size of nerve cell bodies? correct answers 10-100 microns
Which of the following are glial cell types? correct answers A. Microglial cells
B. Astrocytes
C. Schwann cells
D. Oligodendrocytes
E. ALL OF THE ABOVE
, ANSWER: E
The swelling of tissue in the brain is called correct answers Edema
Neural plasticity refers to correct answers Remodeling of connections between neurons
Dorsal roots carry sensory information from the peripheral nervous system to the spinal chord for
transmission to the brain correct answers TRUE
Competitive ligands correct answers Bind to the endogenous ligand site
Neuromodulators bind to a non-competitive site on the receptor correct answers TRUE
Non-competitive neuromodulators can only prevent activation of the receptor, not activate it
correct answers FALSE
An agonist initiates the normal effects of a neural transmitter correct answers TRUE
Clearing neurotransmitter from a synapse after activation is not necessary for subsequent
transmission at that synapse correct answers FALSE
The therapeutic index correct answers Is the separation between the effective dose and a toxic
dose
Antipsychotic drugs, also called neuroleptics, such as chlorpromazine, haloperidol, and loxapine
all act how? correct answers As selective antagonists of dopamine (D2) receptors
Benzodiazepines reduce anxiety by enhancing the activity of GABA correct answers TRUE
Barbiturates, alcohol and benzodiazepines are examples of what category of drug? correct
answers Anxiolytics or depressants
We no longer use barbiturates to treat anxiety because correct answers Their dose-response index
is too narrow
Amphetamines act to depress synaptic activity correct answers False
One of the two ways amphetamines act at a synapse is by enhancing the reuptake of
catecholamines in the presynaptic terminal correct answers FALSE
Neuropeptides are short strings of amino acids correct answers TRUE
Cyclic AMP is a second messenger correct answers TRUE
Transmitter reuptake at a synapse correct answers Saves a cell energy because less new
transmitter has to be made
