biopsychology Flashcards
what is step 1 in synaptic transmission?
information is passed down the axon of the neuron as an electrical impulse known as action potential
what is step 2 in synaptic transmission?
once the action potential reaches the end of the axon it needs to be transferred to another neuron or tissue, by crossing the synaptic gap
what is step 3 in synaptic transmission?
at the end of the neuron, in the axon terminal are the synaptic vessels which contain neurotransmitters
what is step 4 in synaptic transmission?
the electrical (nerve) impulse (action potential) stimulates the release of neurotransmitters from the synaptic vesicles
what is step 5 in synaptic transmission?
neurotransmitters then carry the signal across the synaptic gap. They bind to receptor sites on the photo synaptic cell which then become activated
what is step 6 in synaptic transmission?
once the receptors on the post-synaptic neuron have been activated, they either produce excitatory or inhibitory effects on the post synaptic cell
what is step 7 in synaptic transmission?
exitary neurotrasmitters (e.g neurodrenaline
