the nervous system is the system of neurons, or nerve cells, that relay electrical signals through the brain and body. a nerve cell receives signals from other nerve cells through tree-branch-like extensions called dendrites and passes signals on through a long extension called an axon (or nerve fiber). synapses are places where one cell's axon passes information to another cell's dendrite by sending chemicals called neurotransmitters across a small gap called a synaptic cleft. synapses occur in various locations, including ganglia (singular: ganglion), which are masses of nerve cell bodies. preganglionic nerve cells in the sympathetic nervous system (all of which come from the lateral grey column), use the neurotransmitter acetylcholine, while postganglionic sympathetic nerve cells use norepinephrine. grey matter in the brain and spinal cord is any accumulation of cell bodies and neuropil (neuropil is tissue rich in nerve cell bodies and dendrites). white matter consists of nerve tracts (groups of axons) and commissures (tracts that cross the brain's midline).
