1. Tryptophan - Correct Answer: Amino acid precursor of serotonin.



2. Pain modulation - Correct Answer: Serotonin influences pain perception in the spinal
cord.



3. Nociceptive pain - Correct Answer: Pain from tissue damage, modulated by
serotonin.



4. Neuropathic pain - Correct Answer: Nerve-related pain, influenced by serotonin
levels.



5. Sleep-wake cycles - Correct Answer: Serotonin regulates transitions between sleep
stages.



6. Mood regulation - Correct Answer: Serotonin promotes feelings of well-being and
happiness.



7. Excitatory neurotransmitter - Correct Answer: Neurotransmitter that increases
likelihood of neuron firing.



8. Glutamate - Correct Answer: Most abundant excitatory neurotransmitter in the CNS.

,9. Synaptic integration - Correct Answer: Glutamate integrates synaptic activity across
neurons.



10. Learning and memory - Correct Answer: Processes significantly influenced by
glutamate activity.



11. Ionotropic receptors - Correct Answer: Receptors linked to ion channels for fast
transmission.



12. AMPA receptors - Correct Answer: Mediate fast excitatory transmission, allowing Na⁺
influx.



13. NMDA receptors - Correct Answer: Involved in synaptic plasticity, allowing Ca²⁺ entry.



14. Kainate receptors - Correct Answer: Provide excitatory signals in synaptic
transmission.



15. Depolarization - Correct Answer: Process increasing likelihood of action potential
firing.



16. Dysregulation of serotonin - Correct Answer: Imbalance linked to mood disorders
like depression.



17. Descending pain-inhibitory pathways - Correct Answer: Pathways enhanced by
serotonin to reduce pain perception.

,18. Excitatory effects of serotonin - Correct Answer: Promotes alertness and vigilance in
wakefulness.



19. Metabotropic Glutamate Receptors - Correct Answer: G-protein coupled receptors
modulating neuronal excitability.



20. Neuronal Excitability - Correct Answer: Ability of neurons to fire action potentials.



21. Synaptic Plasticity - Correct Answer: Changes in synapse strength affecting
communication.



22. Glycine - Correct Answer: Inhibitory neurotransmitter in the central nervous system.



23. Glycine Functions - Correct Answer: Regulates motor control and sensory processing.



24. Glycine Receptors - Correct Answer: Ionotropic receptors opening chloride channels.



25. Chloride Ion Channels - Correct Answer: Allow Cl⁻ influx, causing hyperpolarization.



26. Hyperpolarization - Correct Answer: Increased negativity inside neuron, reducing
action potential.



27. GABA - Correct Answer: Main inhibitory neurotransmitter in the CNS.



28. GABA Functions - Correct Answer: Regulates neuronal excitability and promotes
relaxation.

, 29. GABA_A Receptors - Correct Answer: Ionotropic receptors mediating rapid inhibitory
effects.



30. GABA_B Receptors - Correct Answer: Metabotropic receptors mediating slower
inhibitory effects.



Potassium Channels - Correct Answer: Influenced by GABA_B receptors for inhibitory
signaling.



Calcium Channels - Correct Answer: Inhibited by GABA_B receptors, affecting
neurotransmitter release.



Integration of Signals - Correct Answer: Balancing excitatory and inhibitory inputs in the
CNS.



Motor Neurons - Correct Answer: Inhibited by glycine in the spinal cord.



Reflex Modulation - Correct Answer: Glycine's role in controlling reflex actions.



Sedation - Correct Answer: Effect mediated by GABA_A receptor activation.



Anxiety Disorders - Correct Answer: Caused by hyperactivity in neural circuits.



Homeostasis in CNS - Correct Answer: Maintaining balance between excitation and
inhibition.
