6.2: The process of synaptic transmission

Question 1

Briefly outline the process of synaptic transmission (2 marks)

Answer 1

Synaptic transmission involves impulses crossing a synapse between an axon terminal and the adjacent neuron

Question 2

Briefly outline the process of synaptic transmission (2 marks).
Synaptic transmission involves impulses crossing a synapse between an axon terminal and the adjacent neuron.

Answer 2

Neurotransmitters are chemicals released from vesicles on the pre-synaptic neuron from tiny sacs called synaptic vesicles

Question 3

Briefly outline the process of synaptic transmission (2 marks).
Synaptic transmission involves impulses crossing a synapse between an axon terminal and the adjacent neuron.
Neurotransmitters are chemicals released from vesicles on the pre-synaptic neuron from tiny sacs called synaptic vesicles.

Answer 3

They travel across the synapse and lock onto receptor sites on the postsynaptic neuron
