Brain and Nervous System
Brain and Nervous System
A person’s brain and central nervous system are main components of a person’s body and in control of their bodily functions. The brain is much like a computer controlling the functions while the nervous system helps send messages from the brain to the different parts of the body. The brain and nervous system are both very powerful and any adverse health condition that affect either the brain or nervous system can severely impact a person’s ability to function.
Your brain is only about 3 pounds and one of the most important parts of your body. It contains a forebrain, midbrain and hindbrain (back). Your forebrain is in the front of the brain and is the largest part of the brain. It contains the cerebrum which controls how you see pictures as well as your personality, speech, ability to move and feel, intelligence, memory and emotions. The midbrain is located just underneath the forebrain and helps send messages from your brain to your spinal cord. The hindbrain is underneath the cerebrum in your forebrain and also called “little brain” because it looks like a smaller version of your cerebrum. The hindbrain controls your movement, balance, and coordination.
The Nervous System<\h3>
In your brain, you have billions of neurons which send information throughout your body through your nervous system; including from your ears, nose, tongue, eyes and skin to the brain. Your nervous system is like a pathway where these neurons send messages from your brain to the rest of your body. This includes memory, basic body functions and your senses including your sight, hearing, smell, touch and taste.
A variety of adverse health conditions can cause issues with your brain and ultimately your nervous system. The following lists the more common conditions that may affect your brain and nervous system function.
Brain Tumors – brain tumors are a swelling of overgrown tissue in your brain. They can often lead to brain cancer if they are malignant, but they might be benign and cause other issues.
Cerebral Palsy – Cerebral palsy occurs when there is damage or a developmental defect in your brain. It is a condition people are born with and will live the rest of their life dealing with. Cerebral palsy typically results in a lack of physical and intelligent abilities.
Epilepsy – Epilepsy causes frequent seizures which someone will not be expecting. There is no known cause of epilepsy but it can be related to other brain conditions including injury, tumor or infection and is often inherited.
Mental Illness – Another common issue with your brain is mental illness which involves problems with your behavioral and psychological functions that start in the brain. It can be from a chemical imbalance in your brain or structural abnormalities.
