Synaptic Transmission

Question 1

What is a synapse?

Answer 1

The point where one neuron (presynaptic) can send a chemical message to an adjacent neuron (postsynaptic)

Question 2

What are the chemical messages called passed through a synapse?

Answer 2

Neurotransmitters

Question 3

What are the stages of synaptic transmission?

Answer 3

Nerve impulse travels down an axon
Impulse reaches synaptic terminal
Triggers release of neurotransmitters
Neurotransmitters diffuse into synaptic cleft
Ntmitters binds with receptors on dendrite of adjacent neuron
If successful- Ntmitter taken up by post synaptic neuron
