Calcium ions enter the presynaptic neuron resulting in the release of neurotransmitter from the per-synaptic membrane. The neurotransmitter diffuses across the synaptic cleft, fusing with the receptors of the post-synaptic membrane. This changes the sodium channels to open and sodium ions will to flow into the post-synaptic neuron, depolarizing the post-synaptic membrane. This initiates an action potential. After the post-synaptic neuron has been affected, the neurotransmitter is removed by a type of enzyme called cholinesterase. The inactivated neurotransmitter then returns to the pre-synaptic neuron.

Is synaptic transmission always from pre to post synaptic?
Yes
What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
Does synaptic transmission involve electrical information to pass from terminal button to dendrites of another neuron?
No, synaptic transmission is chemical, not electrical.
What is accomplished by synaptic transmission?
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.
The neural message being delivered in a synaptic transmission is carried across the synaptic gap by?
Chemical Substance
What is the chemical responsible for most synaptic transmission in neurons?
acetylcholine
Which is not an event that must occur in a normal cycle of synaptic transmission?
absorption of the neurotransmitter
What occurs when neurons are released into the synaptic cleft?
process of neural transmission starts
The part of the neuron that facilitates synaptic transmission of a signal to another neuron is?
Soma
What are similarities neuro synaptic transmission and nerve conductive have?
both are electrical movement
What is one dietary factor that affects synaptic transmission of nerve impulses?
vitamen b12
A synaptic knob would be located on a?
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
