NERVOUS SYSTEM

WHAT IS THE NERVOUS System?

• The nervous system controls and coordinates your body's actions and helps you sense and respond to changes. It is made up of the brain, spinal cord, and nerves that extend throughout your body. Also your sense organs- eyes, nose, ears, tongue and skin are apart of the nervous system

CENTRAL NERVOUS SYSTEM

• The central nervous system is made of the brain and spinal cord
• The brain is the body's central command and the spinal cord allows your brain to communicate with the rest of you body

PNS (PERIPHERAL NERVOUS SYSTEM)

• Connects the central nervous system to the rest of your body
• Has two main parts- sensory part and the motor part

MAJOR ORGANS

• The Brain- Controls your involuntary actions and thoughts
• The Spinal Cord- Bundle of nerves and is surrounded by protective bones called vertebrae

PARTS OF THE BRAIN

• Largest part is the cerebrum, where you think, problem solve, and where most of your memories are stored. It controls voluntary moments and allows you to use you senses
• Cerebellum processes information from your body and allows the brain to keep track of your body's position and coordinate movements
• Brain stem connects brain to spinal cord
• The medulla is part of the brain stem and controls involuntary movements

HOMEOSTASIS

• Endocrine System- Regulates body activities by producing chemical messengers in glands.
• The brain also tells all the other organs/organ systems what to do

DISEASES

• Alzheimer's disease- it damages the brain and causes a steady loss of memory and of how well you can do your daily activities.
• Parkinson's disease- it happens when there is a problem with certain nerve cells in the brain that control movement. It may also cause problems with balance or walking, as well as confusion and memory loss.
• Peripheral neuropathy- Weakness, numbness, and pain from nerve damage, usually in the hands and feet

CONDITIONS

• A person with a generalized anxiety disorder (GAD) cannot associate his or her fear with a specific event, object, or situation. Feelings of fear are present for not apparent reason. GAD sufferers may experience rapid heart rates, hyperactivity, trouble sleeping, and fatigue.
• Panic disorder is characterized by the occurrence of panic attacks. Attacks can be triggered by events, based on past bad experiences, or they may be unpredictable. Victims may feel shortness of breath, rapid heart rates, sweating, nausea, or a combination of all these symptoms.
