Features of synapse
1. Unidirectional - only pass impulses in 1 direction (pre-postsynpatic neurone)
1 of 7
Features of synapse
2. Inhibition - Cause hyperpolarisation to occur as they make the inside of the postsynaptic membrane to be more negative than the resting potential)
2 of 7
Features of synapse
3. Summation - build up of neurotransmitter in synapse as result of insufficient amounts of neurotransmitter - low -freq APs
3 of 7
Summation:
Spatail - number of presynaptic neurones release enough neurotransmitters
4 of 7
Summation:
Single presynaptic neurone releases neurotransmitter many times over short period
5 of 7
Effects of drugs on synapse
1. Stimulate nervous system - create more AP's in postsynaptic neurones (enhances body's response to impulse)
6 of 7
Effects of drugs on synapse
2. Inhibits nervous system: Creates fewer APs in postsynaptic neurone reducing body's response to impulse
