The Role of The Nervous System in the Human Body
  • The Nervous System controls all of the systems
    in the human body. The brain sends out signals
    to different parts to tell them to move, breathe,
    think, hear, speak etc.
  • There are two parts to the Nervous System
    Central Nervous System (CNS) and the Peripheral
    Nervous System (PNS).
  • The CNS consists of the brain and the spinal cord
    and controls your senses. For example, if you
    touch something very hot, you pull your hand away
    to protect yourself. Thats your nervous system
    telling you to do that.

  • The PNS is all your other nerves in the rest of
    the human body. It is through this system that
    messages are sent from other limbs to the brain.
  • The Nervous System is important for a few
    reasons. It can protect the body from harm,
    keeps us breathing, allows us to learn (reading,
    writing, math, etc), controls movement and
    growth, and feel emotions.

What organs make up the nervous system?
  • The main organs that make up the nervous system
    are the brain and the spinal cord.
  • The brain controls almost all of the actions in
    the body such as movement, behavior and
    responding to the environment. The brain is split
    up into parts, and each part does its own
  • The different structures of the brain are
  • The cerebullum
  • The thalamus
  • The hypothalamus
  • The cerebrum
  • The midbrain
  • The brain stem
  • The pons
  • The brain is shaped like an egg, since it is
    slightly flattened. The brain
  • Also has a sort of split in the middle of it.

Part 2 The spinal cord
  • The Spinal Cord is the pathway for messages to be
    sent the body to the brain and the brain to the
  • The Spinal Cord is located inside of the
    vertebrae and is very long around 43 cm for
    women and 45 cm for men.

How is the nervous system connected to the
skeletal system?
  • The skeletal system is connected to the nervous
    system. The vertebrae, part of the Skeletal
    System protects your spinal cord from damage. The
    skull also protects the brain from injured. Bones
    provide calcium, which is necessary for
    functioning the nervous system

How is the nervous system connected to the
muscular system
  • The muscular system and nervous system help each
    other perform there respective motor and sensory
    duties. Muscles protect the delicate process of
    nerves that run throughout the body and also give
    the brain helpful information. Meanwhile the
    nerves serve between muscles and the director
    brain in full ranges of movement. Both systems
    are also important in digestive processes and
    heart functioning.

How do these organs work together
  • The brain and the spinal cord work together. The
    brain is what sends signals to your spinal cord.
    The nerves branch off of the spinal cord to make
    the Peripheral Nervous System. If there is
    serious damage to the spinal cord, there will be
    a major impact on the structure and function of
    the brain. The brain and spinal cord are made up
    of neurons and other cells that maintain the
    function of what we call, the central nervous

Levels of Organization
  • The Brain is the main organ of the Nervous
    System. It is made up of Nervous tissue which is
    composed of nerve cells, also called neurons.

2 Common Diseases that affect your nervous system
  • Parkinson's disease is a brain disorder. The
    disorder affects your nervous system by movement
    of the dopamine, the dopamine is a chemical that
    carries singles between your nerves to your
    brain. When the cells that produce dopamine die,
    the Parkinson's disorder starts to appear. There
    are currently no cures for Parkinson's disease
    but there are treatments that effect the
    Parkinsons symptoms for a short amount of time,
    but this is all they can do offer symptomatic
    relief. What we dont have is something that
    would actually halt or slow the progression of
    the disease.

2 Common diseases that affect your nervous system
  • Alzheimer's is a common disorder that affects the
    nervous system. The disease occurs when a fiber
    of a nerve cells (neurofibrillary) tangle
    together which spreads through the brain then it
    becomes the first stage of Alzheimer's. At the
    end the damage has spread all through and your
    brain tissue has become a smaller mass. There is
    currently no cure for Alzheimer's. But drug and
    non-drug treatments can help with cognitive and
    behavioral symptoms.

How can you maintain a healthy nervous system?
  • If you want to maintain a healthy nervous system,
    drink lots of liquid because dehydration can
    cause you to be confused or have memory problems.
    Drink water every 15-20 minutes, even just a few
    sips. Smoking, alcoholic beverages and illegal
    drugs can cause brain problems later in life
    Also, make sure you exercise and get a lot of
    sleep every night, which will make you more wide
    awake, allowing you to think more.

Jobs that work with the nervous system
1. Neuropsychologist
  • A neuropsychologist is a special doctor who
    study a patients behaviour, relating to the
  • Whenever Neurosurgeons and psychiatrists need
    help after a brain trauma, they usually call in a

2. Neurologist
A neurologist helps treats disorders in the
brain and nervous system. They do not do surgery
on the brain, unlike the neurosurgeon, but at
times work together.
Fun Facts
  • The left side of the brain controls the right
    side of the body and vice versa!
  • The left side of the brain controls reading,
    speaking and math problems. The right side is
    for your sense of humour and your creative side,
    like art and music.
  • If all neurons in the human body were stretched
    out end to end they would be 600 miles long!

  • Only 4 of brain cells are actually used. The
    rest are kept in reserve.
  • There are more neurons in our bodies than there
    are stars in the Milky Way
