Question 1 (1 point)
Place the following events in the correct sequence.
An action potential is initiated in the postsynaptic membrane of the dendrite.
Sodium gates are opened and sodium ions rush into the dendrite.
A wave of depolarization arrives at the axon terminal.
Neurotransmitters are released into the synaptic cleft.

What is shown by number 2?
C) The fluid inside the neuron (intracellular fluid) is showing that Na+ ions are trapped on the
inside of the neuron, and the inside of the neuron is becoming negatively charged.
C) The fluid inside the neuron (intracellular fluid) shows a high concentration of ions and
an increasing concentration of Na+ ions. The intracellular fluid is becoming positively
charged.
C) This shows a portion of the neural membrane undergoing repolarization. The sodium gates
are closed and the potassium gatcs are open.
This shows a stimulated portion of a neuron membrane. The sodium gates are open and
sodium ions are rushing to the inside of the neuron.
