Electrical Signals in Neurons Crossword Puzzle

QUESTIONS LIST:

• ipsp : a neurotransmitter-caused hyper-polarization of the postsynaptic membrane.
• temporal summation : results from the buildup of neurotransmitter from the rapid, successive release by a single pre-synaptic end bulb.
• spatial summation : results from the buildup of neurotransmitter released simultaneously by several pre-synaptic end bulbs.
• epsp : a neurotransmitter-caused depolarization of the postsynaptic membrane.
• relative : _ refractory period - period of time when a second action potential can be initiated with a very strong stimulus.
• absolute : _ refractory period - time during which a neuron cannot produce an action potential even with a very strong stimulus.
• graded potential : a small deviation from the resting membrane potential that makes the membrane either more or less polarized.
• re polarization : the recovery of the resting membrane potential.
• threshold : the minimum level of depolarization required for a nerve impulse to be generated.
• depolarizing : type of graded potential that results in polarization that is less negative than the resting level.
• hyper polarizing : type of graded potential that results in polarization that is more negative than the resting level.
