Transcript of THE BRAIN
Cerebellum is the Latin word for "little brain".
The cerebellum is located in the base of the brain, right above the brain stem. That is where the spinal cord and the brain meet.
The main function of the cerebellum is to communicate with the other parts of the brain. It also controls coordination and balance.
The cerebellum is important because the spinal cord sends messages to the cerebellum using the sensory system and the cerebellum tells the other parts of the brain what to do.

The brain stem is located in the back part of the brain and connects to the spinal cord.
The brain stem is made up of three parts: mid brain, pons, and medulla oblongata.
The main function of the brain stem is to send signals from the brain to your face and neck. Out of the 12 pairs of cranial nerves in the brain, 10 come from the brain stem. Even though it is small, the brain stem is extremely important because all the signals to/from the body pass through the brain stem.
Most importantly breathing and sleep are controlled in the brain stem.
The frontal lobe is located in the front of the cerebrum.
The frontal lobe is in control of your behavior, emotions, and personality. It is also responsible for problem solving, judgement, and motor function.
If your frontal lobe gets damaged, then your mood will change and you may have difficulties in social settings.
The occipital lobe is located in the back of the cerebrum and above the cerebellum.
The occipital lobe is one of the most important lobes in the human brain, because it controls vision and sight.
WHAT IS ALZHEIMER'S?
Alzheimers is a brain disease that will slowly damage your brain cells. It is the most common form of a major loss memory and attention. Alzheimers shrinks the brain and affects your behavior, memory, thinking and language.
Some symptoms of Alzheimers include:
* You feel cold more
* you forget names of family members
* You cry for no reasons
* You can't solve problems
* You misplace things and forget
* You sleep more then usual
Alzheimers usually gets worse over time. Although there is no cure for Alzheimers, there are several treatments and drugs.
The brain! Could you live without it?
First of all, you should know that the brain is part of the nervous system. It is located in the upper part of your head, inside your skull. Your brain is approximately the size of your two fists held together. The human brain weighs about 3 pounds. As you get older, your brain is still growing. However, when you reach 14 years (females) and 15 years (males) your brain will stop growing.
The brain is made up of a special types of cells. Those cells are called neurons. They are connected with each other and with the nerves in our body. There are more than 100 billion nerves that communicate in trillions of connections called synapses.
The brain is made up of three major parts: (1) cerebrum, (2) cerebellum, and (3) brain stem. In addition, the brain is separated into two hemispheres, the right hemisphere and the left hemisphere.
Let's explore the brain together...
DISEASES OF THE BRAIN
Although the brain is protected by the the thick bones of the skull, the brain could still get diseases.
There are over 400 brain diseases, but the most common diseases or illnesses are: ADHD,
cancer, brain tumor, epilepsy, headache, head injury, i
eizures, stroke, and trauma.
I chose to focus on Alzheimers, because someone in my family has Alzheimers and I thought it would be interesting and relevant to my life to study it.
WHAT HAPPENS TO THE BODY?
Your brain works by sending signals through chemical messengers called neurotransmitters. Neurotransmitters help neurons (brain cells) to communicate with each other. A person with Alzheimers has fewer neurotransmitters than a healthy person. This makes them experience the crazy symptoms.
Also, people with Alzheimers have a lot of proteins and fibers that collect in the brain. This stops the brain cells from working properly and they are not able to send signals to the other parts of the brain.
The parietal lobe is located right above the occipital lobe and behind the frontal lobe in the cerebrum.
The main function of the parietal lobe is sense of touch (texture, temperature, pain, etc.), hand writing and body position.
The temporal lobe is located in the back of the cerebrum.
The main function of the temporal lobe is hearing, memory, and listening. It is also important because it helps with understanding speech, language and pitch.
And now, I would like to thank you and your
for listening, your
for watching, your
for keeping your hands and legs to yourself, and your
for your attention!
SO, DO YOU THINK YOU COULD LIVE WITHOUT YOUR BRAIN?
