1. myelin sheath
2. boutons
3. dendrites
4. soma
Question 2

potassium ions are . . . charged. The total electrical charge on the inside of the membrane is . . .
1. positively, negatively, negative
2. negatively, positively, negative
3. positively, positively, negative
4. positively, positively, positive
Question 3

A. Impulse conduction is a basis for all human behaviour
B. Impulse conduction can contribute to individual differences in behaviour
C. Impulse conduction allows sensory energy to be conducted to the brain
D. Impulse conduction communicates information from the external and internal environments
E. Impulse conduction depends on the presence or absence of neurotransmitters
The correct answer is . . .
1. A, B, D, and E
2. B, C, D, and E
3. A, B, C, and E
4. A, C, D, and E
Question 4
Which term refers to the period whereby no neural impulse can be generated, even with intense stimulation?
1. Action potential
2. Relative refractory period
3. Resting membrane potential
4. Absolute refractory period
Question 5
Which of the following illustrates the correct sequence of events in the process of synaptic transmission?
, 1. Nerve impulse stimulates the terminal bouton - Neurotransmitter diffuses across synaptic cleft - Vesicles attach to the
presynaptic membrane
2. Nerve impulse stimulates the terminal bouton - Transmitter deactivated by bouton - Electrical changes in receiving
cell
3. Nerve impulse stimulates terminal bouton - Neurotransmitters attach to receptors - Neurotransmitters cross the
synaptic cleft
4. Nerve impulse stimulates terminal bouton - Vesicles attach to the membrane - Neurotransmitters are released -
Neurotransmitters attach to receptors on the postsynaptic membrane
Question 6
Which one of the following neurotransmitters helps to control aggression and appetite?
1. Endorphin
2. Gamma-aminobutyric acid
3. Acetylcholine
4. Dopamine
Question 7
The . . . activates the body while the . . . restores normal functioning.
1. autonomic nervous system; peripheral nervous system
2. autonomic nervous system; homeostasis
3. sympathetic nervous system; parasympathetic nervous system
4. sympathetic nervous system; somatic nervous system
Question 8
What effect do endorphins have on the body?
1. They regulate sleep and waking cycles
2. They regulate aggression and muscle tone
3. They regulate motor behaviour
4. They suppress pain
Question 9
The main function of the . . . is to regulate sleep and wakefulness.
1. cerebellum
2. thalamus
3. pons
4. spinal cord
Question 10
Which one of the following statements about the brain is correct?
1. Both hemispheres have to work together for the effective use of language
2. The cerebral hemispheres are connected by the cerebral cortex
3. The left hemisphere regulates the logical and holistic organisation of information
4. The blood-brain barrier protects the brain from being bumped
