chapter 10 Flashcards
action potential comes from where
the brain
from the brain the action potential goes where
the spinal cord
from the spinal cord the action potential goes where
motor neuron
from the motor neuron goes where
the motor neuron of the PNS
from the PNS goes where
the axon terminal
when the action potential goes to the axon terminal what does it stimulate
the opening of voltage gated calcium ion channels
when voltage gated calcium channels are open what diffuses through to the axon terminal
calcium ions
what does calcium in the axon terminal stimulate
synaptic vesicles to fuse to the presynaptic membrane
by synaptic vesicle fusing to presynaptic membrane what happens
the release of ACH into the synaptic cleft
when ACH is released what happens
ACH binds to receptor of chemical gated sodium ion channels
when ach binds to receptor what happens
chemical gated sodium ion channels open
when chemical gated sodium ion channels open what is diffused across the sarcolemma
sodium ions
when sodium ions diffuse across the sarcolemma what happens
creation of new action potential in the muscle fiber
where does the new action potential go
travels down the sarcolemma into the T-tubules
from the T-tubules where does the action potential go
terminal cisternae
