THE BOSS OF YOUR BODY
The brainIt 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.
The Functions of the BrainThe 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.
smell

sight
hearing
SIZE OF THE HUMAN BRAINThe 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.
THE NERVOUS SYSTEMThe 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.
COMPOSITION OF THE BRAINThe 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.
PARTS OF THE BRAINCEREBELLUM
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
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.
The biggest part: The CEREBRUMIs 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.
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.
A Healthy BrainWhat 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.
THANKS AND USE YOUR BRAIN
