10 Cards in this Set

nueron
the cells that transmits the impulses
cell body
contains nucleus and cytoplasm
dendrites
carry the impulse from other neurons to the cell body
axon
a long fiber that carries the impulses away from the cell body
myelin sheath
surrounds the single axon, leaves gaps where the axon membrane is exposed... these are called nodes
as the impulse travels along the axon it can jump from node to node to make the process faster and smoother
resting potential
the cell membrane lets more KA+ ions to leak than NA+ making it negatively charged
resting potential--the electrical charge across the cell membrane of a nueron in its resting state
action potential
the inside of the cell membrane becomes more positive than the outside, reversing the resting potential
threshold
the minimum amount of stimulus that is required to activate a nueron
synapse
the location at which a nueroncan transfer an impulse to another cell
nuerotransmitters
chemicals used by a nueron to transmit an impulse across synapse to another cell
