UNIQUE NUMBER: 548691/846317
Question 1
The term spatial summation refers to . . .
1 the deactivation of neurotransmitters by the enzymes in the synaptic cleft
2 the effect of impulses from different neurons arriving at the same synapse to
reinforce a post-synaptic potential
3 increased frequency of a neuron firing that triggers the release of neurotransmitters
into the synaptic cleft
4 the effect of successive impulses in the same axon to reinforce a post-synaptic
potential
Question 2
The function of the . . . lobe is to help people recognize elements of an object in the
visual field and integrate them into meaningful patterns.
1 Frontal
2 Temporal
3 Parietal
4 Occipital
Question 3
Which one of the following statements about noradrenaline is correct?
1 Noradrenalin is released by the sympathetic nerves and speed up the metabolism
and the release of glucose into the blood
2 A lack of noradrenalin leads to the decline in cognitive functioning seen in
Alzheimer’s disease
3 Noradrenalin is involved in the experience of pleasure and suppression of pain
4 Noradrenalin is associated with an increase in heart rate and contraction of blood
vessels
, Question 4
A low level of serotonin is associated with . . . whereas a low level of dopamine is
associated with . . .
1 muscular spasms; seasonal depression
2 seasonal depression; Parkinson’s disease
3 suppression of pain; aggression
4 mania; Alzheimer’s disease
Question 5
Which term refers to the period whereby no impulse can be generated even with
intense stimulation?
1 Absolute refractory period
2 Action potential
3 Relative refractory period
4 Resting membrane potential
Question 6
The process whereby an impulse moves much faster by jumping from node to node
when travelling through the myelin sheaths is called . . .
1 Myelination
2 Frequency
3 strength and speed
4 salutatory conduction
Question 7
Which neurotransmitter is associated with an increase in heart rate, the contraction of
blood vessels, skeletal muscles and heart muscles?
1 Acetylcholine
2 Serotonin
3 Adrenalin
4 Endorphin
