In an EPSP (excitatory postsynaptic potential), there is a Select one: a. net movement of sodium ions out of the cells. b. net movement of chloride ions into the cells. c. decrease in action potential amplitude. d. local hyperpolarization. e. local depolarization. Topic 11 Graded Quiz 2/11 Question 2 Correct 1.75 points out of 1.75 The figure illustrates the Action Potential. What does "C" represent? Select one: a. repolarization b. depolarization c. local potential d. threshold e. afterpotential Topic 11 Graded Quiz 3/11 Question 3 Correct 1.75 points out of 1.75 Question 4 Correct 1.75 points out of 1.75 Question 5 Correct 1.75 points out of 1.75 Arrange the events of synaptic transmission in correct sequence. (1) sodium ions diffuse into the cell and cause a local potential (2) neurotransmitter binds with receptor on postsynaptic cell (3) neurotransmitter diffuses across the synaptic cleft (4) membrane permeability to sodium ions on postsynaptic cell increases (5) action potential causes release of neurotransmitter Select one: a. 5, 2, 3, 4, 1 b. 5, 2, 3, 1, 4 c. 5, 3, 4, 1, 2 d. 5, 4, 3, 2, 1 e. 5, 3, 2, 4, 1 Saltatory conduction of an action potential means that Select one: a. once one action potential is created, it moves down the axon. b. the whole axon depolarizes at the same time. c. one action potential stimulates the production of a new action potential at the adjacent site. d. an action potential is conducted from one node of Ranvier to the next node.
