Arrange these action potential events in their proper sequence: (1) The neuron is stimulated at the dendrites (2) K+ gates open (3) The neuron is in a polarized “resting” state (4) Na+ gates open (5) The cell is fully depolarized (6) The cell is fully repolarized a. 1, 2, 4, 3, 5, 6b. 3, 1, 4, 5, 2, 6c. 4, 6, 2, 1, 5, 3d. 1, 4, 2, 6, 5, 3

During an action potential of a neuron, the type of ion that enters the cell and causes depolarization is the ion.

Place the following events in excitatory synaptic transmission in order: 1 - A postsynaptic potential is produced. 2 - Voltage-gated calcium channels open and calcium enters the cell. 3 - ACh is released and diffuses across the axon terminal. 4 - A nerve signal arrives at an axon terminal. 5 - Ligand-gated sodium channels open and sodium enters the cell.
