conduction velocity of nerves Flashcards
neuron
a cell that is specialized for the transmission of nervous system impulses
action potentials
when the neuron is stimulated to pass electrical signals along there axons
threshold stimulus
there is a certain point where the volts meet the point that they can evoke an action potential
all or none principle of action potential
the neuron will always fire the same reaction once the stimulus has reached the threshold stimulus
refractory period
the spot has just fired a neuron and the spot cannot fire another
intracellular recording
can be used to display an action potential at one place on the axon of a neuron
extracellular recording
recording happens on two different places on the outside of a neuron or nerve.
biphasic action potential
nerves
bundles of neuron axons that can carry messages to a particular place in the body
biphasic action potential
two phase– the first phase indicates that the electrical impulse is passing the first electrose– the second indicates it has passes the second
compound action potential
trace that results from extracellular recording, because it is of so many individual neurons with different thresholds and stuff and just main point is so many
