Synapses permit the transmission of a nerve impulse from one neurone to another. In doing so, they act as junctions for the nervous system. They can allow...
- a single impulse to stimulate many other neurones into action, allowing one stimulus to create a number of different responses
- multiple impulses from different neurones to combine, forming a single impulse.
I need to appreciate that...
- Neurotransmitter is only produced in the pre synaptic neurone, not the post synaptic neurone
- Neurotransmitter is stored in synaptic vesicles and is released into the synaptic cleft when an action potential travels down the pre synaptic neurone
- Neurotransmitter will diffuse across the synaptic cleft once released by the vesicles
- The neurotransmitter binds with the appropriate receptor molecule on the post synaptic neurone, creating a new action down the axon
Characteristics of the synapse
The basic structure of the synapse leads to some…
