Answer: cause surprise or confusion in (someone), especially by
acting against their expectations
◉ neuron function.
Answer: electrically excitable cells in the nervous system that
function to process and transmit information
◉ dendrites.
Answer: short branched extension of a nerve cell, along which
impulses received from other cells at synapses are transmitted to
the cell body.

◉ neuron electrical charge.
Answer: moving positive and negative ions back and forth through
its outer membrane
◉ action potential.
Answer: occurs when the membrane potential of a specific axon
location rapidly rises and falls
