Housed within the protective
covering of the skull, the brain is
the most complex organ in
the body. It controls
thought, behavior, emotions,
and memory, as well as basic
life functions such
as breathing and heart rate.
The brain consists
of the cortex, brainstem,
and cerebellum. |

The brain is an amazing
three-pound organ that
controls all functions of
the body, interprets
information from the outside
world, and embodies the
essence of the mind and
soul. Intelligence,
creativity, emotion, and
memory are a few of the many
things governed by the
brain. Protected within the
skull, the brain is composed
of the cerebrum, cerebellum,
and brainstem.

The brain receives information through
our five senses: sight, smell, touch,
taste, and hearing - often many at one
time. It assembles the messages in a way
that has meaning for us, and can store
that information in our memory. The
brain controls our thoughts, memory and
speech, movement of the arms and legs,
and the function of many organs within
our body.
The central nervous system (CNS) is
composed of the brain and spinal cord.
The peripheral nervous system (PNS) is
composed of spinal nerves that branch
from the spinal cord and cranial nerves
that branch from the brain.
