Bipolar neurons have one axon and one dendrite.
They emerge from opposite sides of the cell body.
Bipolar neurons are found only as specialized
sensory neurons in the ey
Action potential. Unlike a graded potential, an
action potential is capable of traveling long distances. If a
depolarizing graded potential is
Repolarization. In response to the inflow of Na +,
K + channels open, this time allowing K + on the inside to rush out
of the cell. The movement of K + out of the cell causes
repolarization by restoring the original membrane polarization.
Unlike the re
