OCCTH 585 Neuro Questions With
Complete Solutions.
True or False: Rehabilitation specialists are able to foster functional recovery in the
nervous system without knowledge of the biological basis of injury and repair. - correct
answer.False
It is argued that a biological basis of injury and repair is essential for rehabilitation
specialists to know and understand in order to be effective healthcare providers.
In simple terms, what is neuroplasticity? - correct answer.The brain's ability to change
and adapt.
These brain-based abilities are considered to be a fundamental representation of the
plasticity of the brain. - correct answer.What are learning and memory?
Name the two types of brain plasticity. - correct answer.1 - Structural Plasticity
2 - Functional Plasticity
This term describes the capacity to do something and is an expression of behaviour
after learning. - correct answer.What is skill acquisition?
True or False: Development is a specialized example of neuroplasticity. - correct
answer.True
Embryological maturation occurs at what age in men? At what age in women? - correct
answer.Men - age 23-25
Women - age 20-21
When does aging begin? What begins to occur immediately when aging begins? -
correct answer.- Aging begins when development ends
- Neuronal death
True or False: neurons want to regrow and connect. - correct answer.True
,True or False: In order to function optimally, the brain and nervous system are required
to adapt to the impacts of injury and disease. - correct answer.True
True or False: The CNS is capable of growing new neurons and stemming gaps in the
nervous system - correct answer.False: The CNS is not capable of growing new
neurons and stemming gaps in the nervous system. Thus, there is a limit to recovery.
Which of the following is not strong evidence for neural plasticity?
A) Learning and memory
B) Skill acquisition
C) Development and aging
D) Injury, disease, and recovery
E) None of the above - correct answer.E) None of the above
Learning and memory, skill acquisition, development and aging, and injury, disease,
and recovery all demonstrate the capacity of the brain to engage in neuroplasticity.
This is the location in the neuron in which information is received from incoming inputs. -
correct answer.What are the dendrites?
This is the location in the neuron in which information is integrated and the behaviour of
the cell is decided. - correct answer.What is the cell body?
This is the location in the neuron in which the action potential will be transmitted to the
next target. - correct answer.What is the axon?
Starting with the dendrite, place the following areas of the neuron in order based on how
information flows through the neuron:
A) Dendrites
B) Axon
C) Cell body - correct answer.A - C - B
What is the impact of an excitatory postsynaptic potential (EPSP) on the post-synaptic
cell? - correct answer.An EPSP brings the postsynaptic cell closer threshold and closer
to producing the next action potential.
What is the impact of an inhibitory postsynaptic potential (IPSP) on the post-synaptic
cell? - correct answer.An IPSP moves the postsynaptic cell further from threshold and,
thus, further from producing an action potential.
Place the following steps of the action potential (AP) process in order:
A) AP reaches the end of the axon, activating the synaptic bouton, which contains
synaptic vesicles which house neurotransmitters.
B) Receptor molecules open up ion channels, allowing for ions to flow through.
C) Neurotransmitters diffuse across the cleft towards the postsynaptic cell.
, D) AP activates the synaptic bouton, with activates the synaptic vesicles. The synaptic
vesicles release neurotransmitters into the synaptic cleft.
E) Neurotransmitters bind to receptor molecules on the postsynaptic cells.
F) Either an EPSP or IPSP occurs in the postsynaptic cell, as determined by what type
of ion channel opens up. - correct answer.A - D - C - E - B - F
True or False: Cells receive multiple inputs from multiple sources coming onto the cell
body and dendrites. - correct answer.True
What is the name of the location of cell input integration in the neuron? - correct
answer.Axon hillock
Simply put, what is spatial summation? - correct answer.Multiple impulses from several
neurons at the same time, which will impact whether the threshold for AP is reached in
a cell.
Simple put, what is temporal summation? - correct answer.Several impulses from one
neuron over a period of time, which will impact whether the threshold for AP is reached
in a cell.
True or False: When a cell meets the threshold for an action potential, the response is
an all-or-none reaction. - correct answer.True
Name the three categories of change regarding neuroplasticity. - correct answer.1)
Change in the properties of neurotransmission
2) Change in the properties of the cell
3) Change in the structure/anatomy of the cell
Which category of neuroplastic change would a change in the number of synaptic
vesicles activated during an AP be considered? - correct answer.Change in the
properties of neurotransmission.
Name an implication regarding neurotransmission if the number of synaptic vesicles
activated during an AP changes. - correct answer.If the number of synaptic vesicles
activated during an AP changes, more or less volume of neurotransmitters may be
released in the post-synaptic cleft during an action potential.
Which category of neuroplastic change would a change in the number, size, or shape of
an IPSP or EPSP be considered? - correct answer.Change in the properties of
neurotransmission.
Which category of neuroplastic change would a change in the size or shape of a
neuronal cell be considered? - correct answer.Change in the properties of the cell.
True or False: Changing the size or shape of a cell impacts the density of ions within the
cell but does not impact concentration levels and thus ion flow is not implicated -
