TERM 1 What is the resting potential of a neuron? DEFINITION 1 -70 mv TERM 2 ions DEFINITION 2 charges particles (can be + or -); driven by concentration gradient and voltage gradient TERM 3 concentration gradient DEFINITION 3 charged particles move into regions to occupy them with equal concentration TERM 4 voltage gradient DEFINITION 4 particles move to equalize voltage; opposites attract TERM 5 potential DEFINITION 5 a grouping of charges particles (ions); can be graded TERM 6 decremental DEFINITION 6 the intensity of a potential fades generally as it moves from the point of excitation TERM 7 synaptic potential DEFINITION 7 result from communication across the synapse TERM 8 axon potential DEFINITION 8 "all or none"; nongraded and self-sustaining; full strength all the way down (doesn't loose energy) TERM 9 A- ion DEFINITION 9 "anode" a negatively charged organic ion that stays in the nucleus; for all neurons TERM 10 Na+ ion DEFINITION 10 positively charged sodium ion; normally in the extracellular fluid; very few passive channels for it to pass through
