Impulse causes depolarisation at synaptic knobs • Release of neurotransmitter [NT] from vesicles into synaptic cleft (> 40 known NTs) • Diffusion of NT across synaptic cleft • NT acts on postsynaptic receptors (motor end plates [MEPs] at NMJ) – most NTs excitatory‚ some inhibitory) • Depolarisation of postsynaptic membrane • Conduction of impulse along the next neurone or activation of effector organ Fate of PNS neurotransmitters • Acetylcholine (ACh): broken down in synaptic cleft by the

nursing practise. If such a theory were to be true what treatment would someone with depression be involved in? Also what would a Nurses day to day tasks involve? The Bioamine Theory of Depression is caused by the deficiency of monoamine neurotransmitters and in particular noradrenaline and serotonin. It was discovered in the early 1950’s be researchers that a decrease in monoamines can cause depression and that an increase in monoamines could help to relieve depression (Depression Resource Centre

pathways with different functions. The drugs that block dopamine synapses produce their benefits by acting on neurons in the DA. This system is a set of neurons that project from the midbrain tegmentum to the limbic system (Kalat‚ 1998). This neurotransmitter system in the brain is where most drugs abuse their reinforcing effects that cause addiction (Phllips et al.‚ 2003). Control of this system‚ by the amygdala‚ can influence the incentive value of the sensory property of food and its modulation
