What is the name of the chosen body system?
The name of the body system that I have chosen to research and study is called the Nervous System.

Where is the system located?
The nervous system is broken down into two separate systems: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system consists of the brain and the spinal cord, while the peripheral nervous system is made up of all of the nerves that connect to the rest of the body.

What is the role of the system?
The role of the nervous system in the human body is very important. The nervous system allows us to perform every movement or action that we wish to happen. Whether it be getting out of bed, hanging out with our friends, playing that new video game you love, reading a book, watching television, surfing your favorite websites on the internet, or driving a car, the nervous system is responsible for all of these actions taking place.

What organs make up the body system?

The organs that make up this body system are the neurons, brain (frontal lobes, parietal lobes, occipital lobes, temporal lobe, cerebrum, thalamus, hypothalamus, pituitary gland, cerebellum, midbrain, pons, medulla oblongata), and spinal cord.

What is each organ’s function in this body system?
Neurons: Transfer and interpret signals creating electrical and chemical changes
Frontal Lobes: Do much of the work of complex thinking like planning, imagining, and reasoning
Parietal Lobes: Processes messages such as those related to touch, taste, and temperature (sensory cortex) and also controls movement (motor cortex).
Occipital Lobes: Processes sight
Temporal Lobe: Processes hearing and are also involved in memory retrieval
Cerebrum: Controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing
Thalamus: Processes and coordinates sensory messages, such as touch, received from the body
Hypothalamus: Regulates functions like thirst, appetite, and sleep patterns. It also regulates the release of hormones from the pituitary gland.
Pituitary Gland: Produces hormones involved in regulating growth, puberty, metabolism, water and mineral balance, the body’s response to stress, and much more.
Cerebellum: Helps coordinate and fine-tune movement and balance.
Midbrain: Acts like a complex switchboard, allowing the brain to communicate with the rest of the nervous system.
Pons: Relays messages from the cerebrum to the cerebellum and spinal cord.
Medulla Oblongata: Regulates vital functions of the body, such as heartbeat and breathing.
Spinal Cord: Runs down the inside of the spinal column, connecting the brain with nerves going to the rest of the body.

How do people make sure their body system remains healthy?

There are a couple ways to keep your nervous system healthy and at maximum efficiency. The first way to do this is to ensure optimal nutritional support. In order to do this, you must have an adequate intake of healthy fats and vitamins D and B12. Another way to make sure that your nervous system is kept healthy is to exercise it on a daily basis. The best way to do this is by, on a regular basis, writing as neatly as possible on a piece of paper for about 15 minutes. This is quite effective because it requires intensive use of all of the major components of your conscious motor and sensory apparatuses.

What can go wrong with the chosen body system?
Term
Definition
Cause
Effect
Bell’s Palsy
A form of Neuritis that involves paralysis of the facial nerve causing weakness of the muscles of one side of the face and an inability to close the eye.
Unknown. Recovery may occur spontaneously
Paralysis of the facial nerve;
weakness of the muscles of one side of the face;
may result in inability to close the eye.

Cerebral Palsy
A nonprogressive disorder of movement resulting from damage to the brain before, during, or immediately after birth.
Cerebal Palsy is attributed to damage to the brain, generally occuring before, during, or immediately after birth.
The most common disability is a spastic paralysis.
Sensation is often affected, leading to a lack of balance, and intelligence, posture and speech are frequently impaired. Contractures of the limbs may cause fixed abnormalities.
Other associated features include epilepsy, visual impairment, squint, reduced hearing, and behavioral problems.

Motor Neuron Disease
A progressive degenerative disease of the motor system occurring in middle age and causing muscle weakness and wasting.
Some forms of Motor Neuron Disease are inherited.
Motor Neuron Disease primarily affects the cells of the anterior horn of the spinal cord, the motor nuclei in the brainstem, and the corticospinal fibers.
Multiple Sclerosis
A chronic disease of the nervous system that can affect young and middle-aged adults.
The course of this illness usually involves recurrent relapses followed by remissions, but some patients experience a chronic progressive course.

The myelin sheaths surrounding nerves in the brain and spinal cord are damaged, which affects the function of the nerves involved.
The underlying cause of the nerve damage remains unknown.

Unsteady gait and shaky movement of the limbs (ataxia);
Rapid involuntary movements of the eyes (nystagmus);
Defects in speech pronunciation (dysarthria);
Spastic weakness and retrobulbar neuritis (= inflammation of the optic nerve).

Myalgic Encephalomyelitis (ME)
A condition characterized by extreme disabling fatigue that has lasted for at least six months, is made worse by physical or mental exertion, does not resolve with bed rest, and cannot be attributed to other disorders.
Unknown.
Often occurs as a sequel to such viral infections as glandular fever.

Extreme disabling fatigue that has lasted for at least six months, is made worse by physical or mental exertion, does not resolve with bed rest, and cannot be attributed to other disorders.
Also accompanied by muscle pain or weakness, poor coordination, joint pain, sore throat, slight fever, painful lymph nodes in the neck and armpits, depression, inability to concentrate, and general malaise.

Neuralgia

Maybe due to previous attack of shingles (Postherpetic Neuralgia)
A severe burning or stabbing pain often following the course of a nerve.
Neuritis
A disease of the peripheral nerves showing the pathological changes of inflammation.

Inflammation of the nerves, which may be painful.
Parkinson’s Disease
Degenerative disease process that affects the basal ganglia of the brain.
Associated with a deficiency of the neurotransmitter dopamine
Tremor, rigidity and poverty of spontaneous movements. The patient has an expressionless face, an unmodulated voice, an increasing tendency to stoop, and a shuffling walk.
Sciatica
A common condition arising from compression of, or damage to, a nerve or nerve root.
Usually caused by degeneration of an intervertebral disc, which protrudes laterally to compress a lower lumbar or an upper sacral spinal nerve root.The onset may be sudden, brought on by an awkward lifting or twisting movement.
Pain felt down the back and outer side of the thigh, leg, and foot. The back is stiff and painful. There may be numbness and weakness in the leg.

What would happen to the individual if something went wrong with the system?
If your nervous system failed, you would lose feeling of every part of your body. Touch prevents you from destroying your body and tearing it apart. If you lose touch, which is when your nervous system fails, you will unknowingly tear your body to shreds, and your whole body will ultimately fail and collapse.

Could a person survive without this body system?
No, a person could not survive without a nervous system. Although the nervous system allows the body to function properly by use of thought and action, it also uses the brain stem to control automatic actions like your heartbeat and breathing: actions that you do without even thinking.
