The synaptic transmission is where the communication between the terminal button and the dendrite occur. What happens is the impulse moves along the axon and release neurotransmitter from the end plate of the presynaptic neuron and are diffused across the synaptic cleft. This creates a depolarization of the dendrites of the postsynaptic neuron. When that happens the postsynaptic's sodium channels to open and start the action potential. Once the channels are open an enzyme called cholinesterase is released from postsynaptic membrane and it acts to destroy the neurotransmitters. When they are destroyed the sodium channels close and begins recovery.

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
What is the small space separating pre and post-synaptic neurons?
The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.
What causes the synaptic delay?
The synaptic delay is caused by the process of neurotransmitter release, diffusion across the synaptic cleft, binding to receptors on the post-synaptic neuron, and the propagation of the electrical signal through the post-synaptic cell. This series of events takes time to occur, leading to the delay in signal transmission across the synapse.
What are similarities neuro synaptic transmission and nerve conductive have?
both are electrical movement
Which is not an event that must occur in a normal cycle of synaptic transmission?
absorption of the neurotransmitter
The part of the neuron that facilitates synaptic transmission of a signal to another neuron is?
Soma
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of neurons. They store and release neurotransmitters during synaptic transmission in order to pass signals to other neurons or target cells.
