Nervous System

By Natalie Swerdlow

The Cerebellum is located behind the brain stem

Function for Each Organ and Cerebellum

Brain: The brain serves as the control center for the body and is responsible for storing all information including everything that you have done in the past, what you are doing right now, and what you will do in the future.

Spinal cord: The spinal cord is the main pathway for information to reach the brain and peripheral nervous system.

Peripheral nerves: The primary role of the peripheral nerves is to connect the spinal cord and brain to the arms, legs, organs, and skin to allow movement and feeling.

· Helps maintain the body’s sense of balance and directs the muscular movement through sensory information

· The cerebellum signals the body to move and determines the extent and timing of individual muscles

· Makes postural adjustments to maintain balance and is responsible for coordinated movements

What is the Nervous System and its Functions?

· Allows an animal to adjust and change to its environment

· The nervous system allows the body to move, have emotions, and have thoughts

· Receives signals from the outside world and inside of the body through senses. Through this, the brain which is part of the nervous system must be able to make decisions and process information to help the body

The nervous system is where dreams are taken place when you sleep

Types of Cells for the Cerebellum

· Nerve cells are a main component of the nervous system and allow us to think, and dream

· Granule cells account for more than half of the neurons in the entire brain. These cells receive information from mossy fibers

· Neurons are the functional unit of the nervous system

Diseases Associated With the Nervous System

· Multiple sclerosis

· Alzheimer’s disease is mostly diagnosed in older people but a rare form can be found in people in their thirties, forties, and fifties. Alzheimer’s disease begins by destroying the neurons in parts of the brain that deal with memory. Symptoms include memory loss and thinking skills are gradually lost. Because of this, daily tasks are soon forgotten and the ability to recognize familiar objects and people are gradually lost. Although there is no cure, treatments such as medication can be used to slow the progression of the disease.

· Parkinson’s disease

· Epilepsy

Could You Live Without the Nervous System? What Are Some Medical Advancements?

· You would not be able to live without the nervous system because if you didn’t have any part of the nervous system you wouldn’t be able to move and respond to the body’s needs. All thinking and emotions would not be possible without the brain which is part of the nervous system.

· Some medical advances in the nervous system include medicines to treat diseases associated with the nervous system.

How Does the Nervous System Interact with Other Organ Systems?

· The nervous system interacts with the digestive system because the brain controls drinking and feeding behaviors

· Bones from the nervous system provide essential calcium for the nervous system

· The brain monitors the respiratory volume and blood gas levels
