18
Q

Which of A or B shows chemical communication?

A

A

19
Q

In the lock and key process of neural communication, what is the ‘lock’?

A

receptor site on post-synaptic dendrite

20
Q

In the lock and key process of neural communication, what is the ‘key’?

A

neurotransmitter

21
Q

What stimulates a pre-synaptic terminal button to release neurotransmitters into the synapse?

A

When an action potential reaches the axon terminals, the synaptic vesicles release neurotransmitters into the synapse.

22
Q

What effect does an excitatory neurotransmitter have?

A

Post-synaptic neuron more likely to fire an action potential/ message continues

23
Q

What effect does an inhibitory neurotransmitter have?

A

Post-synaptic neuron less likely to fire / inhibits message
