Flashcards in intro to neurones, nerve conduction and synaptic transmission Deck (18):
receives input from other neurones and convey graded electrical activity signals passively to the soma
what part of the neurone is this?
metabolic part of neurone. contains nucleus, mitochondria etc. Integrates incoming signals which are then conducted passively to the axon hillock.
soma (cell body)
site of initiation of the " all or nothing" action potential
conducts output signal as action potential to other neurones
site of communication between neurones
neurone with 1 neurtie?
neurone with 1 neurite that splits
neurone with 2 neurites
neurone with 3 or more neurites
in an action potential in neurones, what channels open in the upstroke part?
in an action potential in neurones , what channels open during the downstroke?
what does myelin do?
makes conduction faster
what is saltatory conduction?
when an action potential jumps from one of Node or Ranvier to the next in myelinated axons
name 3 types of synapse?
what separates the pre and post synaptic membranes?
where is the neurotransmitter stored?
in the vesicles
many inputs converge upon a neurone to determine output
