a- increased Cl- influx into presynaptic terminals

b- increased Ca ++ influx into presynaptic terminals

c- decreased response of postsynaptic receptors

d- hyperpolarization of presynaptic terminals

a- is due to increased Ca ++ concentration in postsynaptic neurons

b- is due to increased Ca ++ influx into presynaptic neurons

c- results from slow prolonged stimulation of synapse

d- causes fatigue of the synapse

a- oxygen lack

b- alkalosis

c- acidosis

d- prolonged activity of synapse

a- inhibition of the postsynaptic neuron

b- depolarization of the postsynaptic neuron

c- initiation of an action potential

d- block of ligand-gated cation channels

a- opening of K + channels

b- opening of ligand-gated cation channels

c- closure of Cl- channels

d- closure of potential-gated Ca ++ channels
