Nervous System Background Info
The Nervous System
The nervous system is mainly comprised of nerves and the brain. The brain is the control center for the system and resides inside the skull. In addition, the spinal column which contains the most imperative nerves resides in the spine.

In Short...
The nervous system consists of:

• the brain
• the spinal cord
• the nerve fibers that transmit messages from the brain throughout the body
The nervous system is responsible for all physical reactions and telling each body part to move when and where. The nerves are also responsible for feeling pain and reaction time to stimuli. Additionally, the brain is responsible for all emotions and feelings.
System Importance
The nervous system is important for proper functioning of the body in that it ensures that reactions occur efficiently and sends signals through the body that result in every bodily function.
Potential Health Issues
Some of the many potential health issues associated with the nervous system are paralysis due to nerve damage, all psychological disorders, and epilepsy.
How Exercise Affects the Nervous System
Short Term Effects
The immediate effects of exercise are on the neurotransmitters. It causes complex signals to pass through the neurons in the brain. This alerts the brain for learning and makes information easier to retain.
Long Term Effects
Exercise stresses the muscles which creates growth factors. This contributes to brand new brain cells and it increases the number of pathways for oxygen, energy, and to remove waste from the brain.
Aerobic Exercise
Aerobic exercise is the most beneficial type of exercise on the nervous system. It improves cognition for all people, but the cognitive abilities of aerobically active children particularly stand out against those who are not aerobically active.
Anaerobic Exercise
Anaerobic exercise has no proven effect on the nervous system, however it still is a very important part of a balanced exercise plan and positively affects other body systems.
Inactivity's Effect
Inactivity makes the nerve cells reduce growth, as depicted. It reduces the effectiveness of the areas of the brain associated with motor skills and learning.

In short...
It's good for the brain!
Exercise improves your cognitive function and makes you more alert, as well as reduces stress.
