independent study presentation

my independent study

• My independent study topic is the nervous system.
• I wanted to learn the many facts and injuries about the nervous system.
• I want to be a doctor when I grow up so this really helps me.

My progess

• I started with neurons and nerve cells and their functions, diseases etc.
•  I went a little deep into neurons and I decided to do an overview.
• I started a little slow then I started to catch up. 
• In the future I'd like to study the brain and it's functions, diseases etc 

Parts of a neuron

• A typical neuron possesses a cell body (often called the soma).
• It also has dendrites and axons.
• The generic term for dendrite or axon is neurite.

More details

• An axon is a special cellular extension that arises from the cell body.
• The cell body of a neuron frequently gives rise to multiple dendrites.
• The axon may branch hundreds of times before it terminates

Neuron's functions

• The neurons transmit information from the brain to the body.
• They are responsible for telling the body what to do.
• Without the speed of neurons, are reactions or actions will be much slower.

How neurons are the same as other cells

• Neurons are surrounded by a cell membrane.
• Neurons have a nucleus that contains genes.
• Neurons contain cytoplasm, mitochondria and other organelles.

How many of these cells are in everything's body

• The number of neurons in the brain varies from species .
• For humans, most estimates have ranged between 86 - 100 billion.

The Brain

• The brain is an organ located inside your head.
• The brain and the spinal cord form the central nervous system.
• This complex system controls everything we do. 
• Each part of the brain has a different job.
• There are 3 parts of the brain: cerebrum, cerebellum, and brainstem

Cerebrum

• The cerebrum uses information from our 5 senses .
• It also controls our emotions, and our ability to talk, think, read.
• Then it tells us how to respond.

Cerebellum

• The cerebellum is located under the cerebrum at the back of the brain.
• The cerebellum is located under the cerebrum at the back of the brain.

Brainstem

• The brain stem connects the brain and the spinal cord.
• The brainstem controls functions such as breathing, blood pressure, etc.

How the spinal cord helps the brain

• The spinal cord is the pathway that connects the brain to the nerves.
• This is important because the brain could use the spinal cord to send info
