PYC1501 ASSIGNMENT QUESTION AND ANSWERS 2013 - 2017
2 central nervous system
3 neurotransmitters
4 parasympathetic nervous system
Question 4
Sensory or afferent neurons are responsible for
1 conducting messages from the spinal cord and the brain to the
muscles and glands
2 catalysing an action potential
3 carrying messages from the environment to the spinal cord
and brain
4 ensuring that an impulse is conducted through the axon to the
boutons
Question 5
Which of the following is not a function of the hypothalamus?
1 The regulation of motor activity
2 The regulation of emotions
3 The regulation of sleep and wakefulness
4 The regulation of water intake
Question 6
While walking to school Khensani was startled by very
loud explosions from a local factory Referring to the
charactenstics of impulse conduction, please indicate
which one of the following statements is correct when
considering the scenario above
1 The frequency of impulse conduction increased because of
the loud explosion
2 The magnitude of impulse conduction increased because of the
loud explosion
3 In comparison to softer sounds, a loud explosion leads to

PYC1501 ASSIGNMENT QUESTION AND ANSWERS 2013 - 2017
4 The loud explosion is more intense stimulus and it causes larger
changes in the membrane potential
Question 7

whereas in an unmyelinated axon it is known as conduction
1 resting membrane - generator potential
2 postsynaptic potential - salutatory
3 axon hillock - refractory penod

Question 8
The gaps that separate the myelin sheaths and contain the sodium
and potassium ion channels required for impulse conduction are
known as the
1 terminal boutons
2 nodes of Ranvier
3 channel
4 synaptic cleft
Question 9
Which of the following neurotransmitters is associated with
seasonal depression?
1 Acetylcholine
2 Adrenalin
3 Serotonin
4 Dopamine
Question 10
During the refractory period
