The process of Synaptic transmission

Question 1

What is the first step?

Answer 1

-Begins in the post synaptic neuron
-action potential is sent down the axon
-to the pre synaptic terminal

Question 2

What is the second step?

Answer 2

causes neurotransmitters in vesicle only in the pre synaptic neuron to release in the synaptic cleft.

Question 3

What is the third step?

Answer 3

neurotransmitters diffuse across the synapse and bind to there specific receptor site in post synaptic neuron.

Question 4

What is one reaction that can happen when they attach to the receptor site?

Answer 4

neuron is ready to fire a impulse

Question 5

What is another reaction?

Answer 5

reuptake
NS recycled back into vesicle in pre synaptic neuron.

Question 6

What are the two types of neurotransmitters?

Answer 6

Excitatory and Inhibitory

Question 7

What is Excitatory neurotransmiiters?

Answer 7

-bind onto the PSR the PSC becomes positvively charged
-most likely the PSC will fire and impulse
-increases the brain activity in the CNS

Question 8

What does the Inhibitory neurotransmitter do?

Answer 8

-when it binds onto the PSR the PSC becomes negatively charged
-reduces the likelyhood of PSC firing a impulse
-decreases the brain activity in the CNS

Question 9

What is summation?

Answer 9

-when inhibitory and excitatory influences are added together
-mainly inhibitory,neg charge, decreasing brain activity
-Mainly excitatory, positively charged, increasing brain acitvity.
