- Define an action potential.arrow_forwardDraw and label an action potential, indicating the ion movements responsible for the rising phase and the falling phase.arrow_forwardAssume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.arrow_forward
- Describe depolarizing of graded potential? Explain with an example?arrow_forwardIf a postsynaptic cell has synapses from five different cells, and three cause EPSPs and two of them cause IPSPs, give an example of a series of depolarizations and hyperpolarizations that would result in the neuron reaching threshold.arrow_forwardDescribe the ion concentration gradients across the plasmamembrane of a neuron at resting potential.arrow_forward
