Nervous system

The main structures include:


Spinal Cord

Brain Stem

Central Nervous System

Peripheral Nervous System


Nervous system levels of organization


To maintain homeostasis in the nervous system the brain has sensors which determine when things are not normal in the body. When this happens the brain then sends signals back out to cause reactions which will bring body levels back to normal. If homeostasis breaks the nervous system may not be able to control bodily functions resulting in extreme body temperatures, a change in eating habits, and dehydration.

Interactions with other Body Systems

Skeletal System

The nervous system works in conjunction with other body systems to help maintain homeostasis. For example, the skeletal system helps project the nervous system as the skull protects the brain and the vertebrae protects the spinal cord. The brain and spinal cord are vital in order for the body to function properly.

Cardiovascular System

The nervous system works with the cardiovascular system to deliver oxygen, hormones, nutrients and white blood cells around the body by pumping blood, and it removes waste products which is very helpful when the brain sends messages to throughout the body. The heart is keep beating by electrical impulses from the nervous system.

Endocrine System

The nervous system works with the endocrine system to signal the release of hormones. The hormones provide feedback to the brain to affect many natural processes that aid in the development of systems such as the reproductive system. Also the hypothalamus, which is located in the brain, controls the pituitary gland and other endocrine glands.
