Question

Put the following events of the synapse and graded potential in order to generate an action potential. Assign a number 1-6. _________The neurotransmitter binds to a receptor on the dendrite. ________Sodium enters the dendrite and neuron cell body: generating an EPSP. _____ An action potential arrives at the axon terminal of the presynaptic neuron. ______ When the EPSP reaches threshold and action potential fires. _______ An influx of calcium initiates the release of neurotransmitter. ______ The neurotransmitter diffuses across the synapse: from presynaptic neuron to postsynaptic neuron.

Explanation / Answer

an influx of calcium initiates the release of neuro transmitters the neuro transmitter binds to the receptor on a dendrite the action potential arrives at the axon terminal of the presynaptic neuron the neurotransmmiter diffuses across the synapse;from presynaptic to postsynaptic neuron sodium enters the dendrite and neuron cell body generate an epsp when the epsp reaches threshold and action potential fibres
