,Question 1
Stimulus intensity is to impulse frequency as . . . is to the amplitude
of the impulse.
1. a synapse
2. conduction speed
3. intensity of light stimulus
4. diameter of the nerve fibre
Question 2
The contrast between two poles of a neuron is called . . .
1. an action potential
2. potential difference
3. resting membrane potential
4. a postsynaptic potential
Question 3
The electrical charge resulting from the difference between the
positive and negative ions outside and inside the cell membrane
results in . . .
1. a threshold
2. the action potential
3 the resting membrane potential
4. the refractory period
Question 4
During the group discussion on myUnisa group site, one student
mentions that neurons can send impulses continuously. This
statement is . . .
1. correct, because neurons are never inactive
2. incorrect, because the resting potential must be restored before
another impulse can fire
3. incorrect, because impulses cannot be conducted during the absolute
refractory period
4. correct, because the refractory period prevents over-stimulation of the
nervous system
,Question 5
Which term refers to the period whereby no neural impulse can be
generated, even with intense stimulation?
1. Action potential
2. Absolute refractory period
3. Relative refractory period
4. Resting membrane potential
Question 6
The peripheral nervous system is made up of the . . .
1. brain and spinal cord
2. neurons and organs that lie beyond the brain
3. central nervous system and sympathetic nervous system
4. somatic nervous system and autonomic nervous system
Question 7
The autonomic nervous system is made up of the . . .
1. brain and spinal cord
2. organs and glands
3. sympathetic and parasympathetic nervous system
4. central nervous system and somatic nervous system
Question 8
When the sympathetic nervous system is activated . . .
1. the body inhibits digestion and lungs expand to absorb more
oxygen
2. the digestive processes increase and there is decreased lung action
3. the pupils contract and muscles relax
4. the body restores blood supply to the skin and reduces blood pressure
Question 9
The relationship between emotion and autonomic physiological
arousal forms the basis for the use of a polygraph (lie detector) test. A
polygraph . . .
1. measures the lies told by the person being tested
2. records psychological changes in relation to the lies being told
3. makes people respond differently during questioning
4. monitors the physiological changes when a person lies
, Question 10
The . . . lobe produces more generalised and integrated behaviours.
1. frontal
2. temporal
3. parietal
4. occipital
Question 11
Which sleep stage is characterised by poor motor coordination when
a person is woken up?
1. Phase 2 sleep
2. Phase 3 sleep
3. Phase 4 sleep
4. D-sleep
Question 12
Which sleep disorder refers to a condition when a person has
breathing difficulties during sleep and wakes up gasping for breath?
1. Insomnia
2. Catalepsy
3. Sleep apnea
4. Narcolepsy
Question 13
A sleep disorder called narcolepsy is characterized by an inability to
move, which occurs just before one falls asleep or when waking up in
the morning. This answer is . . .
1. correct
2. Incorrect. The statement refers to catalepsy
3. incorrect. Narcolepsy is characterized by breathing difficulties during
sleep
4. incorrect. Narcolepsy is characterized by an overwhelming need to sleep
Question 14
Opiate drugs are . . . and work by . . . in the body.
1. timulants; decreasing the action of inhibitory neurons
2. depressants; producing nausea and insensitivity to pain
3. stimulants; mimicking other drugs
4. hallucinogens; increasing the release of dopamine
