Question 5

resting potential

Answer 5

inactivated state of neuron; negative charge and does not let positive charged ions in

Question 6

presynaptic cell

Answer 6

fires and releases neurotransmitters from its terminal buttons

Question 7

postsynaptic cell

Answer 7

detect the presence of neurotransmitters and cause channels to open

Question 8

excitatory postsynaptic potential

Answer 8

positive charges from outside allowed in cell - called depolarization, increase chance cell will fire

Question 9

inhibitory postsynaptic potential

Answer 9

positive charges let out - hyperpolarized, decrease chance a cell will fire
