Function of the nervous system
Provide
rapid
and
precise
communication
between different parts of the
body
via the
action
of
neurones
View source
Neuron
Specialised for
intercellular
communication
Displays substantial variation in
size
and
shape
but all have the same basic
structure
View source
Dendrites
Highly
branched
processes
extending
from
cell body
Form
synapses
with
adjacent neurones
Respond to
external stimuli
Convey
incoming
information to cell body
View source
Cell body
Large
nucleus
and prominent
nucleolus
Nissl
bodies
Numerous
mitochondria
View source
Axon
Rapidly
propagates
signal
from
cell body
towards
axon
terminals
Specialised to
conduct
action potentials
PNS
-
myelinated
or non-myelinated
CNS
-
myelinated
View source
Terminal boutons
Form
synapses
with other
neurones
or
effector organs
Communication junctions
(eg
neuromuscular junctions
)
Here
electrical
signal converted to
chemical
signal
Neurotransmitters
released and convey
message
to next cell in pathway

Cells of the nervous system
Neuron
Neuroglia
View source
Neuroglia
Protect
and
support
neurons
View source
Neuroglia in the CNS
Ependymal
cells
Astrocytes
Microglia
Oligodendrocytes
View source
Ependymal cells
Simple
ciliated cuboidal
epithelium
Line
fluid-filled
cavities
in
brain
(
ventricles
) and
spinal canal
No
basement membrane
View source
Astrocytes
Named for their
star-shape
Large
, numerous
glial
cells
Form the
blood-brain
barrier
Regulate
the
chemical
environment
View source
Microglia
Named for their
small
size
Phagocytic
capacity
Remove
invading
microbes
and
dead
cells from
CNS
View source
Oligodendrocytes
Predominant
neuroglia
of
white
matter
Form
myelin sheaths
around all
CNS
axons
Provide
structural
and
metabolic
support
View source
Neuroglia in the PNS
Satellite
cells
Schwann
cells
View source
Schwann cells
Form
myelin sheaths
around
PNS axons
Provide
structural
and
metabolic
support
Non-myelinated
axons are
enveloped
in
cytoplasm
of
Schwann cell
Myelinated
axons are gradually
wrapped
by the
Schwann cell membrane
to create a
myelin sheath
View source
Satellite cells
Flattened
cells that cover the
surface
of neuronal cell bodies
Provide
structural
and
functional
protection
