Central Nervous System
contains the brain and spinal cord.
Peripheral Nervous System
includes all the nerves out-
side the brain and spinal cord.
Meninges
protective mem-
branes that cover the brain and
spinal cord
White Matter
portions of the ner-
vous system that appear white in
color because they are composed
of myelinated axons
Grey Matter
portions of the
nervous system that appear grey in
color because they are composed
of neuron cell bodies and unmyelinated axons.
Sensation
immediate and basic
experience generated as sensory
stimuli fall on our sensory systems .
Perception
the higher-order
process of integrating, recognizing,
and interpreting complex patterns
of sensations.
Aphasia
deficit in the ability
to use or comprehend language
caused by brain damage.
Neuron
cells of the nervous
system that are specialized for the
reception, conduction and trans-
mission of electrochemical signals
Dendrites
branched
projection(s) of a neuron that
functions as the receptive area
of a neuron.
Axon
projection of a neu-
ron that functions to conduct
electrical impulses away from a
neuron’s cell body
Nodes of Ranvier
gaps
between adjacent myelin
segments on an axon.
Demyelination
the loss of
myelin insulating neurons.
Congenital Analgesia
disease
in which patients do not sense
pain.
Diabetic Neuropathy
disorder
in which nerves of the body are
damaged due to high blood sugar
levels resulting from diabetes
