Unit 2 Flashcards
To monitor electrical activity that is triggered when one hears their own name, researchers would make use of what ?
An EEG
In order to experience the pain of a sprained ankle, _____ must first relay messages from your ankle to your central nervous system.
sensory neurons
A drug that blocks the re-uptake of a particular neurotransmitter is called a(n)
antagonist
Increasing excitatory signals above the threshold for neural activation will not affect the intensity of the action potential. This indicates that the neuron’s reaction is
an all-or-nothing response
The somatic nervous system is a component of the ______ nervous system.
peripheral
When ACh is blocked, the result is
muscular paralysis
Depolarization of the neural membrane can create a(n)
action potential
Mr. Smith thought his daughter had fallen down the stairs. His rate accelerated, blood pressure rose and he began to perspire heavily. His state of arousal was activated by his _____nervous system.
sympathetic
Drugs that block the reuptake of serotonin will thereby increase the concentration of the molecules in the
synaptic gaps
The minimum level of stimulation required to trigger a neural impulse is called the
threshold
The limbic system structure that regulates hunger is called the
hypothalamus
The successful functioning of children who have experienced surgical removal of an entire cerebral hemisphere best illustrates the value of
plasticity
Though there is no single control center for emotions, their regulation is primarily attributed to the brain region known as
limbic system
Which region of the brain appears to have its oldest evolutionary history?
brainstem
In the brain, I outnumber neurons. I also provide nutrients and help remove excess neurotransmitters I am a
glial cell
Which of the following is typically controlled by the right hemisphere?
emotion
Information is most quickly transmitted from one cerebral hemisphere to the other by the
corpus callosum
In order to pinpoint the location of a tumor, the neurosurgeon electrically stimulated parts of the patient’s sensory cortex. If the patient was conscious, which of the following was probably experienced?
a sense of having the skin touched
Jessica experienced difficulty keeping her balance after receiving a blow to the back of the head. It is likely that she injured her
cerebellum
The association areas are located in the
cerebral cortex
which term happens along side action potential
depolarized
when the cell is at rest, it is;
polarized
anti-depressants block the WHAT of serotonin
reuptake
the cell fires when there is more excitatory than inhibitory signals (true or false)
true
