What is number 1 and 4 pointing to?
1= dendrites
4= nodes of Ranvier
What does MS do to the signal being sent? Why?
It doesn't send the signal because it gets lost because demyelination is taking place making neurons not receive signals
What are SSRI’s? (refer to Anatomy of a Synapse wksh)
Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants

What is the function of Oligodendrocytes/Schwann cells?
making myelin sheath in the central nervous system (CNS)
What is the function of Microglial cells?
