Central nervous
system:
− Brain.
− Cerebellum.
− Spinal chord.


Neurons

The neuron is the
basic processing unit
of the CNS.

There are 100 billion
neurons in the brain.
Each neuron is
connected to an
average of 1000
synapses.

Glial cells

They are the
supportive cells of the
CNS. They feed,
support, clean, and
protect the neural
tissue.

The proportion
neuron/glia can go up
to 4:1 in some places.

The brain

The brain consists of:
− Brainstem.
− Cerebellum.
− Cerebrum.

Brainstem

Three basic
components:
− Medulla oblongata, or
medulla.
− Pons.
− Mesencephalon.

It is the fundamental
connection between
the upper cerebrum
and cerebellum to the
spinal chord.
