CNS and PNS
communication with body
synapse
synaptic terminal
node of ranvier
action potential
membrane potential
anions
cloride ions (Cl-), higher conc. extracellular
proteins (intracellular)
cations
Sodium ions (Na+), higher conc. extracellular
Potassium ions (K+), higher intracellular conc.
sodium potassium pump (3 Na+, 2 K+), maintains membrane potential
threshold
depolarization
hyperpolarization
will send signal
leak channels (for K+)
voltage gated ion channels (Na+ and K+)
ways to speed up
larger diameter of axon, less resistance to ion flow
myelin sheaths
saltatory conduction
lots of lipid, poor conduction
chemical synapse
synaptic vesicle
voltage gates Ca2+ channel
