1
A _______ between the axon of one neuron and the dendrite of another neuron
where information is transmitted
  • Synapse
  • Interneuron
  • Neurotransmitter
2
The ff. are ways to remove neurotransmitter/s from the receptor EXCEPT?
  • Enzymes in the receptors break down the neurotransmitter.
  • Reuptake returns the neurotransmitter to the vesicles, where it is
    stored.
  • The neurotransmitter diffuses away from the synapse.
  • By increasing the number of action potentials, the neurotransmitter will automatically detach from the receptor
3
Fast-acting communication between
neurons
  • Amino acids
  • Peptides
  • Amines
  • Cathecolamines
4
Fight-or-flight" response
  • Amines
  • Peptides
  • Cathecolamines
  • Amino acids
5
Involved in many functions including mood, sleep,
and attention.
  • Peptides
  • Amino acids
  • Cathecolamines
  • Amines
6
Have longer-lasting effects than other types
  • Peptides
  • Amines
  • Amino acids
  • Cathecolamines
7
The first NT to be discovered
  • Serotonin (SE)
  • Dopamine (DA)
  • Gamma-Amino Butyric Acid
    (GABA)
  • Acetylcholine (ACh)
8
State the name of this abbreviation: PTSD
Post Traumatic Stress Disorder
9
Related to stress reduction and behavioral
regulation, and also causes PTSD if a person lacks this NT
  • Acetylcholine (ACh)
  • Dopamine (DA)
  • Serotonin (SE)
  • Oxytocin (OT)
10
This is most active in the midbrain, and the hypothalamus. It's also related to addiction and Parkinson's disease
  • Dopamine (DA)
  • Acetylcholine (ACh)
  • Serotonin (SE)
  • Norepinephrine (NE)
11
Produced in the brainstem, and causes bipolar disorder when there is a shortage
  • Norepinephrine (NE)
  • Acetylcholine (ACh)
  • Oxytocin (OT)
  • Gamma-Amino Butyric Acid
    (GABA)
12
Shortage of Gamma-Amino Butyric Acid
(GABA) results to what disease in the following?
  • Schizophrenia
  • ADHD
  • Seizures
  • Depression
13
What autoimmune disorder that targets the neuromuscular junction, specifically acetylcholine
receptors, impairing communication between nerves and muscles, characterized by fluctuating
muscle weakness that worsens with activity but improves with rest or treatment, most often
affecting the eyes, face, throat, and sometimes the limbs?
  • Addiction
  • Epilepsy
  • Fibromyalgia
  • Myasthenia gravis
14
One way of terminating neurotransmitters from the receptor cells in the synaptic cleft is by reabsorption and reused by the nerve cell that release it, a process called?
Reuptake
15
The non-transmissible cells of the nervous system are the?
  • Neuroglia ( Glial cells )
  • Neurotransmitter
  • Synapse
16
The part of the neuron that transmits impulses away from the cell body is the ______?
  • Soma
  • Dendrite
  • Node of ranvier
  • Axon
17
Which outcome best explains the role of GABA in preventing epileptic seizures?
  • It enhances inhibitory control, reducing neuronal overactivity
  • It excites cortical neurons
  • It increases serotonin levels
18
A patient has multiple sclerosis. Which glial cell is most directly affected, and how would this impact neural transmission?
  • Schwann cell - slower sensory conduction in the PNS
  • Oligodendrocytes - Impaired saltatory conduction in the CNS
  • Ependymal cells - CSF production
19
Why is carbidopa used together with levodopa as medication for managing the motor symptoms of Parkinson's disease?
  • Carbidopa directly converts into dopamine in the brain, doubling the effect of levodopa.
  • Levodopa is used to treat the movement
    symptoms seen, while carbidopa helps to reach the brain
  • Carbidopa strengthens the dopamine receptors, making them more sensitive to levodopa.
20
Deficiency of _______ results in Insomnia:
  • Glutamate
  • Serotonin
  • GABA
  • Dopamine
