Question 1

The part(s) of the neuron that (is) are responsible for receiving information signals, (is)
are called . . .

1. dendrites
2. boutons
3. myelin
4. all of the above

Question 2

The part of the neuron that facilitates synaptic transmission of a signal to another neuron
is
...

1. dendrite
2. terminal bouton
3. soma
4. myelin sheath

Question 3

The electrical charge resulting from the difference between the positive and negative ions
outside and inside the cell membrane is called . . .

1. the action potential
2. a high threshold
3. the resting membrane potential
4. the refractory period

Question 4

Which of the statements about the following diagram is/are correct?

1. In accordance with the all-ornone-law, neurons A, B, C and D will
conduct an impulse at exactly the same speed, or not at all.
2. In comparison with neurons A, C and D, neuron B can conduct impulses at the
highest
speed and
amplitude.
3. In comparison with neurons A, B and C, neuron D will conduct impulses at the
highest frequency.

4. 1 & 3

Question 5

The opening across which one neuron communicates with another neuron is known as the
...

1. threshold
2. channel
3. synaptic cleft
4. membrane

Question 6

The tutor asks the group what the term “refractory period” means. One of the students
said that it is a phase when the neuron is not ready to fire. Evaluate this answer. The
statement is . . .

1. not correct because the refractory period refers to the phase between the action
potential and the resting potential
2. not correct because the refractory period refers to the phase when the neuron is
ready to fire
3. partially correct, because the neuron is unable to fire during the absolute refractory
period
4. correct, because the neuron is not ready to fire during the refractory period.

Question 7

The tutor asks the group to draw up a flow chart to illustrate the process of synaptic
transmission. Is this an appropriate way to illustrate synaptic transmission?

1. no, because a diagram should be used to represent the process
2. yes, because a flow chart should provide a great deal of detailed information
3. yes, because a flow chart should provide an overview of the process it illustrates
4. yes, because the flow of information goes in one direction only

Question 8

Which of the following illustrates the correct sequence of events in the process of synaptic
transmission?

1. nerve impulse stimulates bouton, neurotransmitter diffuses across synaptic cleft,
vesicles attach to presynaptic membrane

2. nerve impulse stimulates bouton, transmitter deactivated by bouton, electrical
changes in receiving cell
3. nerve impulse stimulates bouton, vesicles attach to membrane,
neurotransmitters
released and attach to receptors on postsynaptic
membrane
