neurons
cells in the nervous system that communicate with one another to perform information-
processing tasks
cell body
the part of the neuron that coordinates information-processing tasks and keeps the cell
alive
dendrite
the part of a neuron that receives information from other neurons and relays it to the cell
body
axon
the part of a neuron that transmits information to other neurons, muscles, or glands
myelin sheath
an insulating layer of fatty material
glial cells
support cells founds in the nervous
synapse
the junction or region between the axon of one neuron and the dendrites or cell body of
another
sensory neurons
neurons that receive information from the external world and convey this information to
the brain via the spinal cord
motor neurons
neurons that carry signals from the spinal cord to the muscles to produce movement
internerurons
neurons that correct sensory neurons, motor neurons, or other interneurons
resting potential
the difference in electric charge between the inside and outside of a neuron's cell
membrane
action potential
an electric signals that is conducted along a neuron's axon to a synapse
refractory period
the time following an action potential during which a new action potential cannot be
initiated
terminal buttons
knoblike structures that branch out from an axon
neurotransmitters
chemicals that transmit information across the synapse to a receiving neuron's
dendrites
receptors
parts of the cell membrane that receive the neurotramsmitter and initiate or prevent a
new electric signal
