Nervous System By: Sarah Dayhuff 3/30/17 E block

The nervous system is made of the structures that control the actions and reactions of the body in response to stimuli from the environment.

The nervous system has two parts: Central and Peripheral

Lou Gehrig's disease-A nervous system disease that weakens muscles and impacts physical function.

Treatment: physical therapy, medication Prevented: eating colorful fruits and vegetables

Aphasia-A language disorder that affects a person's ability to communicate.

Treatment: speech therapy Prevent: Regular exercise, healthy weight, fruits and vegetables, limited consumption of salt and fats.

Voluntary processes- the actions that you can control

Involuntary processes- happen automatically, no control over them

How it works with the other systems:

Muscular: receptors in muscles provide the brain with information about body position and movement.

Skeletal: Bones provide calcium, which is needed for the proper functioning of the nervous system.

Cardiovascular: The brain regulates heart rate and blood pressure.

Respiratory: The brain monitors respiratory volume and blood gas levels. The brain regulates respiratory rate.

- Stimuli( sound,touch,light, taste, hearing) is received by a sensory neuron.

It is then taken to the Central Nervous system.

Then the Central Nervous System interprets the information.

The 'instructions' are then sent through motor neurons to effectors

The effectors then respond.

Cerebrum- controls voluntary movements and allows you to sense touch, light, sound, odors, taste, pain, heat, and cold.

Cerebellum- processes information from your body.

Brian stem- connects your brain to your spinal cord, the medulla, controls involuntary processes
