what is
saltatory conduction
?
the generation and transmission of nerve
impulses in mammals
transmission of an
action potential
in myelinated neurones
what is the '
all of nothing
' law?

?
resting potential
draw a labelled diagram of a
polarised
membrane at
resting potential
; to include all membrane proteins and the distribution of all ions
how is the resting potential maintained?
generating an
action potential
describe the changes in the membrane potential that result in
depolarisation
and an action potential being generated
label the stages of the graph
why is an action potential an example of
positive feedback
?
the structure and roles of synapses in
neurotransmission

cholinergic synapse
, including the
synaptic bulb

neurotransmitters
at the synapse

spatial summation
what is
summation
?
