When an action potential reaches the end of a cell, the passage of the action potential onto the next cell occurs with the help of _______ -sodium -all of the alternatives are correct -neurotransmitters -potassium

Stimuli below this intensity will result in no response in a neuron. Resting Membrane Potential Electrical Threshold Repolarization Action potential

.... For the remaining questions, the following scenario applies. You might want to draw it. Both neuron X and neuron Y are pre-synaptic to neuron Z. Neuron X secretes a neurotransmitter that opens sodium ion channels. Neuron Y secretes a neurotransmitter that opens potassium ion channels. Answer the following questions in the order given. The neurotransmitter from neuron X will neuron Z and is O depolarize, excitatory O hyperpolarize, excitatory O depolarize, inhibitory O hyperpolarize, inhibitory QUESTION 17 The neurotransmitter from neuron Y will neuron Z and is O depolarize, inhibitory depolarize, excitatory O hyperpolarize, excitatory O hyperpolarize, inhibitory QUESTION 18 Click Save and Submit to save and submit.
