Synaptic Transmission- Process And Structure

Question 1

What is step 1 of the process of synaptic transmission?

Answer 1

An electrical impulse travels along the axon of a presynaptic neuron to the terminal branches.

Question 2

What is step 2 of the process of synaptic transmission?

Answer 2

When the electrical impulse gets to the terminal branches it stimulates the synaptic vesicles which contain neurotransmitters

Question 3

What is step 3 of the process for synaptic transmission?

Answer 3

The neurotransmitters are released from the synaptic vesicles and travel across the synaptic cleft. This is when the electrical impulse has been changed into a chemical impulse

Question 4

What is step 4 of the process of synaptic transmission?

Answer 4

There are receptors on the dendrites of the postsynaptic neuron. If the neurotransmitters are the correct shape , then they can fit into the receptors on the dendrites of the postsynaptic neuron

Question 5

What is step 5 of the process of synaptic transmission?

Answer 5

The connection between the neurotransmitter and the receptor can cause an electrical impulse to be created in the dendrites of the postsynaptic neuron. However, this depends on whether the neurotransmitters are excitatory or inhibitory

Question 6

What is the step 6 of the process of synaptic transmission?

Answer 6

Excitatory neurotransmitters increase the likelihood of an electrical impulse in the postsynaptic neuron. Whereas inhibitory neurotransmitters decrease it.

Question 7

What is the last step (step 7) of synaptic transmission?

Answer 7

Once the neurotransmitter has been released from the postsynaptic receptor site reuptake happens
