Which of the following illustrates the correct sequence of events in the process of synaptic transmission?
1. Nerve impulse stimulates the terminal bouton - Neurotransmitter diffuses across synaptic cleft - Vesicles attach to presynaptic membrane
2. Nerve impulse stimulates the terminal bouton - Transmitter deactivated by bouton - Electrical changes in receiving cell
3. Nerve impulse stimulates the terminal bouton - Neurotransmitters attach to receptors - Neurotransmitters cross synaptic cleft
4. Nerve impulse stimulates the terminal bouton - Vesicles attach to the membrane - Neurotransmitters are released - Neurotransmitters attach to receptors on postsyanaptic membrane
Nerve impulse stimulates the terminal bouton - Neurotransmitters attach to receptors - Neurotransmitters cross synaptic cleft.
