VERSION!!
1. If a patient has a disorder affecting the autonomic nervous system, which
bodily functions are likely to be impacted?
Voluntary muscle movements like walking and talking
Sensory perception of touch and pain
Involuntary functions such as heart rate and digestion
Cognitive functions such as memory and reasoning
2. If a patient has a damaged peripheral nerve, what potential effects might they
experience related to the organization of the PNS?
Enhanced cognitive function
Loss of sensation or motor function in the affected area
Improved synaptic transmission
Increased reflexes in the spinal cord
3. A pre-synaptic neuron releasing NT onto a post synaptic neuron in this zone
does not always cause an AP to form in?
discharge zone
conductive zone
ossification zone
facilitated zone
4. Describe the role of neuroglia in the nervous system.
Neuroglia form the myelin sheath around axons.
, Neuroglia transmit electrical signals between neurons.
Neuroglia are responsible for the production of neurotransmitters.
Neuroglia support and protect neurons, providing structural
support and aiding in the maintenance of homeostasis.
5. In a scenario where a neuron is experiencing increased synaptic input, how
would the facilitated zone be affected?
The facilitated zone would become less active, reducing action
potential generation.
The facilitated zone would remain unchanged regardless of synaptic
input.
The facilitated zone would inhibit action potential generation.
The facilitated zone would become more active, increasing the
chances of action potentials.
6. If a neuron is demyelinated, how would this affect the process of saltatory
conduction?
Demyelination would only affect neurotransmitter release at synapses.
Demyelination would disrupt saltatory conduction, leading to
slower nerve impulse transmission.
Demyelination would enhance saltatory conduction, making impulses
travel faster.
Demyelination would have no effect on saltatory conduction.
7. Describe the role of reflexes in the functioning of the nervous system.
Reflexes are slow responses that require conscious thought and
decision-making.
