excitatory and inhibitory neurotransmitters/summation Flashcards
1
Q
what do excitatory neurotransmitters do
A
depolarise the postsynaptic membrane, making it fire an action potential if the threshold is reached
2
Q
example of an excitatory neurotransmitter
A
acetyl choline - binds to receptors to cause an action potential in postSM
3
Q
what do inhibitory neurotransmitters do
A
hyperpolarise the postSM which prevents it from firing an action potential
4
Q
example of an inhibitory neurotransmitter
A
acetyl choline - binds to receptors in heart and can cause potassium ion channels to open on the postSM
5
Q
A
