Synaptic Transmission

Question 1

Synaptic Transmission definition

Answer 1

Process when neighbouring neurons

Communicate with eachother

by sending chemical messages across

the synaptic cleft that separates them

Question 2

Neurotransmitters def

Answer 2

Brain chemicles released from synaptic vesicles

Relays signals across synapse from one neuron to another

Can have excitatory or inhibatory function (seratonin)

Question 3

Excitation

Answer 3

When neurotransmitter (adrenaline)

Increases the positive charge of the post- synaptic neuron

This increases the liklihood the neuron will fire

and pass on the electrical impulse

Question 4

Inhibition

Answer 4

When a neurotransmitter (seratonin)

Makes the charge of the post synaptic neuron negative

Decreases liklihood neuron will fire

And pass on electrical impulse

Question 5

Synapse

Answer 5

Junction between 2 neurons

Includes:

presynaptic neuron

Synaptic cleft

Post synaptic receptor site

Question 6

Vesicles

Answer 6

Small sacs

At the end of the presynaptic neuron

Contains neurotransmitters

That will be released into a synapse

Question 7

Pre- synaptic neuron

Answer 7

The transmitting neuron

Before the synaptic cleft

Question 8

Post- synaptic neuron

Answer 8

Neuron that is recieving the info

At the synapse
