Basic components: neurons ~ transmit neural impulses (action potential, cell body cell"s life support center, axon sends out neural impulses, excitatory making it easier for neuron to fire. Inhibitory makes it harder for neuron to fire: dendrites, multiple action potentials are needed to trigger a neuron to fire. Impulses are chemical and have electrical processes: glial cells ~ provide support (ex. by aiding in neural impulse conduction) Issues with glia may result in neurodegenerative disease like alzheimer"s: ben barres.
