Synapses Flashcards
where do synapses occur?
they occur between neurones and target cells
what can target cells be?
other neurones, muscle cells or secretary cells
where does electrical transmission along axons terminate?
at the synapses and is relayed to the next cell via chemical messengers (neurotransmitters)
where are the chemical messengers stored?
they are stored In vesicles in the pre-synaptic neurone
what happens when an action potential reaches the vesicle?
their contents are released into the synaptic cleft and bind to receptors on the post-synaptic membrane
what do receptors bind to the post-synaptic membrane stimulate?
a depolarisation or hyper-polarisation, contraction in post-synaptic muscle cells and secretion in post-synaptic secretory cells
