Synaptic Transmission

Question 1

what is synaptic transmission

Answer 1

the process by which one neuron communicates with another

Question 2

what is neural networks

Answer 2

its how Neurons communicate with each other within groups

Question 3

are neurons separated

Answer 3

yes

Question 4

what are neurons seperated by

Answer 4

the synapse

Question 5

what is a synapse

Answer 5

a tiny gap between neurons where the neurons are connected

Question 6

how are signals within the neurons transmitted

Answer 6

electrinoically

Question 7

how are signals between neurons transmitted (across the synapses)

Answer 7

chemically

Question 8

what is the presynaptic terminal

Answer 8

the end of the neuron

Question 9

what does the electrical transmitters trigger when it reaches the presynaptic terminal

Answer 9

it triggers the release of neurotransmitters from the synaptic vesicles

Question 10

what are synaptic vesicles

Answer 10

tiny sacs in the presynaptic terminal

Question 11

how many directions can an impulse take

Answer 11

1

Question 12

what happens once the neurotransmitter crosses the synapse

Answer 12

it gets taken up by a postsynaptic receptor site to go to the next neuron

Question 13

where is the post synaptic receptor site located

Answer 13

at the end of the synapse

Question 14

what are neurotransmitters

Answer 14

chemicals that diffuse across the synapses to the next neuron in the chain

Question 15

what are two common neurotransmitters in psychology

Answer 15

acetylcholine and serotonin

Question 16

where is acetylcholine found and what does it do

Answer 16

where a motor neuron meets a muscle - causing muscles to contract

Question 17

what does serotonin do

Answer 17

Affects mood and social behaviours

Question 18

what is excitation

Answer 18

when a neurotransmitter increases the + charge of the postsynaptic neuron therefore increasing action potential

Question 19

what is inhibition

Answer 19

when a neurotransmitter increases the - charge of the postsynaptic neuron therefore decreasing action potential

Question 20

what does excitation do in terms of mood

Answer 20

linked to active mood and emotions

Question 21

what does inhibition do in terms of mood

Answer 21

helps control mood

Question 22

what is the sum of excitatory and inhibitory influences

Answer 22

action potential

Question 23

in order for the action potential of the postsynaptic neuron to be triggered, what is needed

Answer 23

Excitatory and inhibitory influences to be summed together and reach a certain threshold
