Document Summary
Multiple sclerosis is caused by the immune system attacking myelin. We would have a much larger head: neurons communicate with each other at synapse. Chemical being transferred from one cell to the next: neurotransmitters are synthesized in cell bodies stored in axon terminals and stiumlated for release by action potentials and calcium, vesicle. Hours to day: action potential travels quickly vesicle takes a lot of time, usually low concentration of calcium inside. Binds to proteins for vesicles to fuse with plasma membrane. Distance between clef and next receptor: neurotransmitters bind to receptor ( ligand-gate) channels in the postsynaptic membrane and change ion flow and therefore membrane potential. Ligand is a chemical that binds a receptor. Organized constellation of cells specialized for repeated conduction of electrical signals between cells. All processes and cell bodies of sensory and motor neurons that occur outside of cns. Bring info to and from other parts of body from cns.
