ACTION POTENTIAL QUIZ

Action potential = ____________ - Answer - Nerve impulse Action potential - Answer - Is unidirectional in that information is always receive down the dendrites and transferred to another cell through the axon terminal Action potential stages - Answer - ng potential arization arization ng potential Resting potential (-70 mv) - Answer - -State or neuron is and when not transmitting a signal -A resting neuron is polarized Depolarization ( voltage charges from -60 mv to a +30 mv) - Answer - Stimulus (Ach) causes +Na to enter cell Repolarization (+30 mv back to - 70 mv) - Answer - Sodium pump closes and potassium pump open, pumping out +K ions until resting potential voltage of -70 mv is reached Resting potential - Answer - The cell returns to its normal resting potential state Continuous propagation - Answer - -is continuous, with no jumping -no Myelin Sheaths -slower speed Salitory propagation - Answer - -Cover it with myrlin sheaths -Spaces in between myelin sheaths is called nodes of Randvier -sheath
