This type of change can Select one: a. be a local potential. b. be an action potential. c. be a consequence of an increase in the permeability to Na+. d. result in repolarization. e. be a local potential and a consequence of an increase in the permeability to Na+. Question 2 Correct 1.75 points out of 1.75 Flag question Question text Depolarization of the nerve cell membrane occurs when there is a rapid influx (inflow) of Select one: a. potassium ions. b. chloride ions. c. calcium ions. d. sodium ions. e. proteins. Question 3 Correct 1.75 points out of 1.75 Flag question Question text 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 Question 4 Correct 1.75 points out of 1.75 Flag question Question text Neurotransmitters are released from the Select one: a. epineurium. b. synaptic cleft. c. presynaptic terminal. d. postsynaptic membrane. e. calcium channels.
