Transcript brain 3 - futuristicferfuson

The brain is the center of the nervous system in all vertebrate and most
invertebrate animals.[1] Some primitive animals such as jellyfish and
starfish have a decentralized nervous system without a brain, while
sponges lack any nervous system at all. In vertebrates the brain is located
in the head, protected by the skull and close to the primary sensory
apparatus of vision, hearing, balance, taste, and smell.
The cerebrum is the biggest portion of the brain. This part,
the cerebrum deciphers troubles and composes your
needs. It’s kind of like a Gene in a bottle that grants wishes!
This is where all the thinking takes place. The language you speak
and the expression of emotions come from your cerebrum.
Especially from your cerebral cortex that is on the outside of your
cerebrum.

Your body movements are synchronized and harmonized
by the cerebellum. It takes a cerebellum to hit a home run.
Your cerebrum will tell your hands and arms to move, but
your cerebellum will coordinate for precision in order for
you to drive it out of the yard. Yea!
Here’s a fun fact: The cerebellum makes up only 10% of the
brain, but holds up to half the neurons in the entire brain
In vertebrate anatomy the brainstem (or brain stem) is the
posterior part of the brain, adjoining and structurally continuous
with the spinal cord. The brain stem provides the main motor and
sensory innervations to the face and neck via the cranial nerves.
Though small, this is an extremely important part of the brain as
the nerve connections of the motor and sensory systems from
the main part of the brain to the rest of the body pass through the
brain stem. This includes the corticospinal tract (motor), the
posterior column-medial lemniscuses pathway (fine touch,
vibration sensation and proprioception) and the spinothalamic
tract (pain, temperature, itch and crude touch).
A longitudinal fissure separates the human
brain into two distinct cerebral hemispheres,
connected by the corpus callosum. The
sides resemble each other and each
hemisphere's structure is generally mirrored
by the other side. Yet despite the strong
similarities, the functions of each cortical
hemisphere are different
Broad generalizations are often made in
popular psychology about certain functions
(eg. logic, creativity) being lateralized, that
is, located in the right or left side of the
brain. These ideas need to be treated
carefully because the popular lateralizations
are often distributed across both sides.
A well-balanced brain keeps away several ailments such
as stress, anxiety, loss of memory, dementia, paralysis
etc. But how to keep the brain healthy? Provide it with all
the necessary ingredients that it needs – the minerals,
the vitamins, and oxygen as well as water too.
