so how does a message travel from neuron to neuron?
a message travels from neuron to neuron at amazing speeds and this happens to do the parts that make up the neuron.
and the parts of that make up the neuron are the dendrites, axons, cell bodies,axon terminals, and myelin sheaths.
when a neuron is stimulated, ions move across the membrane, this causes excitability. the result. the result is spreading to other membrane regions, moving away from the original site, sending messages over the nerve.
so then the message goes along the axon through the myelin sheath and that increases the speed of the message?
yes! and the message goes toward the axon terminals and that causes the release of neurotransmitters
like epinephrine, that helps the message "jump" across the synaptic cleft.
exactly! the message impulse that "jumped" to the dendrites to the cell body then the axons and axon terminals and that starts the whole process over again.
