Question

4 Multiple sclerosis is a demyelinating disease, in which the patient's immune system attacks and destroys that form the myelin sheath in the central nervous system. What types of symptoms would you expect f a disease? Why? Would Schwann cells or oligodendrocytes be affected? Explain. 5 The bacterium Clostridium tetani produces a toxin called tetanospasmin, the causative agent of the disease tetanus. The toxin prevents the release of inhibitory neurotransmitters in the CNS and so blocks the resultin IPSPs they would normally generate. What are some of the functions of inhibitory synapses? Considering th what symptoms would you expect from the disease tetanus, and why? (Hint: Imagine trying to stand up if a the muscles in your lower limb contracted at the same time.) Certain inhaled anesthetic agents are thought to open Cl- channels in the membranes of postsynaptic neurons in the brain, an effect that causes IPSPs. Why might this action put a person "to sleep" during anesthesia? Predict what would happen if the calcium ion channels in the axon terminal were blocked. Explain.
