Question 1

neurotransmitters

Answer 1

chemical substance produced by neuron that carried neural message from one neuron to another

Question 2

synapse vs synaptic gap

Question 3

excitatory neurotransmitter

Answer 3

stimulate or activate postsynaptic neurons to perform function
ake them more likely to fire

Question 4

inhibitory neurotransmitter

Answer 4

blocks/ pevents postsynaptic neurons from firing

Question 5

glutamate

Answer 5

excitatory neurotransmitter
in CNS
involved in perception, learning, memory, thinking, movement

Question 6

GABA

Answer 6

inhibitory neurotransmitter
CNS
finetune neurotransmission and maintain it at optical level
without inhibitory effect activation of postsynaptic neuron would be out of contorl and cause overstimulation

Question 7

lock and key process

Answer 7

each has nt has a distinct chemical shape
nt searches for correctly shaped receptor on postsynaptic neuron
must be a precise match to bind
binding unlocks postsynaptic response to nt (excitatory or inhibitory)

Question 8

neural communication is….

Answer 8

an electrochemical process
