NEUROSCIENCE
Neurons vs glia
Structures and functions of parts of neuron (e.g. dendrites, soma, axon,
terminals)
The electrochemical process of neural communication
Resting potential vs threshold of excitation (AKA summation threshold)
Sodium & potassium ions (channels, charges, distribution at rest vs firing)
Action potential (ion movement & distribution, changes in voltage inside vs
outside)
Neurotransmitters, vesicles, events at synapse
Multiple sclerosis
Glutamate vs GABA
Organization of nervous system (see “flowchart” of organization hierarchy)
Central, peripheral, somatic, autonomic, sympathetic, parasympathetic nervous
systems
