fEATURES OF SYNBAPSEY 0.0 / 5 ? Applied SciencefrgBTEC NationalAQA Created by: AmanCreated on: 06-05-14 20:36 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 7 of 7
