Select the answer that correctly orders the events that occur when a nerve signal reaches the axon terminal. (1) The neurotransmitters bind to receptors on the postsynaptic cell. (2) The postsynaptic cell is stimulated to initiate a nerve signal. (3) Synaptic vesicles release neurotransmitters via exocytosis. (4) Neurotransmitters diffuse across synaptic cleft.

(3) Synaptic vesicles release neurotransmitters via exocytosis.

(4) Neurotransmitters diffuse across synaptic cleft.

(1) The neurotransmitters bind to receptors on the postsynaptic cell.

(2) The postsynaptic cell is stimulated to initiate a nerve signal.

Explanation:

Neurons transmit nervous impulses. These cells connect to each other by the process of synapsis. Neurons are composed of the cellular body, dendrites, and the axon that conducts the electrochemical signals.  As it occurs in every synapsis the presynaptic neuron sends information to the postsynaptic one. Vesicles carrying the neurotransmitter fuse with the presynaptic membrane and release the molecule by exocytosis to the intercellular space. This chemical substance travels through the synaptic cleft to the junctional area of the other neuron and binds to its receptors in the postsynaptic membrane. This binding produces depolarization of the cell. An action potential is initiated and spreads to the rest of the membrane depolarizing it.
