The document explains the structure and functions of the human brain, describing it as a complex organ that controls various bodily functions and processes information. It details the brain's components, including different lobes, the central nervous system, and its composition of gray and white matter. Additionally, it emphasizes the importance of maintaining a healthy brain through proper nutrition, exercise, and mental activities.

1. THE BOSS OF YOUR BODY

2. The brain
It runs the show and controls just about everything
you do, even when you´re asleep.
It looks like a big gray sponge with wrinkles.
It fills the whole of the top half of your head.

3. The Functions of the Brain
The human brain is a complex organ that allows us to
think, move, feel, see, hear, taste, and smell.
It controls our body, receives information, analyzes
information, and stores information (our memories).
The brain produces electrical signals, which together
with chemical reactions,let the parts of the body
communicate.

5. SIZE OF THE HUMAN BRAIN
The average human brain weighs about 1.3 kilos.
At birth, the human brain weighs less than a half of a
kilo and as a child grows, the number of cells remains
relatively stable.
The human brain reaches its full size at about 6 years
of age.

6. THE NERVOUS SYSTEM
The brain and spinal cord make up the central
nervous system.
The brain is connected to the spinal cord, which runs
from the neck to the hip area. The spinal cord carries
nerve message between the brain and the body.
This is called the nervous system.
It controls our breathing, digesting food, blood
circulation, etc.

8. COMPOSITION OF THE BRAIN
The brain consists of gray matter (40%) and white
matter (60%) contained within the skull.
Brain cells include neurons and glial cells.
The cranium (the top of the skull) surrounds and
protects the brain.

9. PARTS OF THE BRAIN
CEREBELLUM
It regulates balance, posture,
movement, and muscle
coordination.
CORPUS COLLOSUM
- A large bundle of nerve fibers
that connect the left and
right cerebral hemispheres.
In the lateral section, it looks
a bit like a “C” on its side.
_ MEDULLA OBLONGATA
- It controls automatic functions
including heartbeat, breathing,
etc.
PITUITARY GLAND
- A gland that secretes
hormones. Is very small.
- It controls growth

10. SPINAL CORD
- A thick bundle of nerve fibers
that runs from the base of
the brain to the hip area,
running through the spine
(vertebrae)
PITUITARY GLAND
- A gland that secretes
hormones. Is very small.
- It controls growth
. PONS
- The part of the brainstem that
joins the hemispheres of the
cerebellum and connects the
cerebrum with the
cerebellum.

11. The biggest part: The CEREBRUM
Is the thinking part of the brain. Controls your voluntary muscles
OCCIPITAL LOBE OF THE
CEREBRUM
- It contains the centers of
vision and reading ability
(located at the back of the
head)
. PARIETAL LOBE OF THE
CEREBRUM
-It contains important sensory
centers .
TEMPORAL LOBE OF THE
CEREBRUM
- Contains centers of hearing and
memory (located at the sides of
the head)
FRONTAL LOBE OF THE
CEREBRUM
- Regions of the cerebral
hemispheres. Used for
reasoning, emotions,
judgement, and voluntary
movement.

12. SPINAL CORD
- A thick bundle of nerve fibers
that runs from the base of
the brain to the hip area,
running through the spine
(vertebrae)
- PONS
- Connects the cerebrum with
the cerebellum.
HYPOTHALAMUS
- Controls temperature.If your
body is too hot, the
hypothalamus tells it to
sweat. If you are too cold, the
hypothalamus gets you
shivering.

16. A Healthy Brain
What can you do for your brain?
- Eat healthy foods. They contain potassium and
calcium, two minerals that are importanbt for the nervous
system.
- Get a lot of playtime (exercise)
- Wear a helmet when you ride a bike or play other sports
that require head protection
- Don´t drink alcohol, take drugs or use tobbaco.
- Use your brain by doing challenging activities, such as
puzzles, reading, playing music, making art, or anything
else that givews your brain a workout.
