Neuron

✔A nerve cell; the basic building block of the nervous system



Dendrites

✔A short branched extension of a nerve cell, along which impulses received from
other cells at synapses are transmitted to the cell body.



Axon

✔The long threadlike part of a nerve cell along which impulses are conducted
from the cell body to other cells.



Soma (cell body)

✔Bulbous, non-process portion of a neuron or other brain cell type, containing the
cell nucleus.



Myelin

✔A whitish insulating sheath around many nerve fibers, increasing the speed at
which impulses are conducted.



Action Potential

Glial Cells

✔Cells that surround neurons and provide support for and insulation between
them.



Synapse

✔A junction between two nerve cells, consisting of a minute gap across which
impulses pass by diffusion of a neurotransmitter.



Vesicles

✔Store various neurotransmitters at the axon terminal that are released at the
synapse.



Neurotransmitters

✔A chemical substance that is released at the end of a nerve fiber by the arrival of
a nerve impulse and, by crossing the synapse, causes the transfer of the impulse to
another cell.



Reuptake

✔The reabsorption by a neuron of a neurotransmitter following the transmission of
a nerve impulse across a synapse.
