The Function of The Nervous System
The nervous system transmits signals to parts of the body so they can preform specific functions.
Central Nervous System and Peripheral Nervous System
Central Nervous System: The central nervous system contains two parts, the brain and the spinal cord. The brain contains over 100 billion nerve cells. The Spinal cord is housed in the backbone.
The Peripheral: The peripheral nervous system is divided into two parts, the somatic nervous system and the autonomic nervous system.

The Functions of The Major Regions of The Cerebral Hemispheres, Diencephalon, Brain Stem and The Cerebellum
Cerebral Hemispheres: The brain has two sides, The left side is related to langue and logic while the right brain is related to emotion and feelings.
Diencephalon: The Diencephalon’s function is regulating wakefulness and controlling the autonomic nervous system.
Brain Stem: The Brain Stem’s job is to regulate, heart rate, breathing, sleeping and eating.
Cerebellum: The Cerebellum’s job is to receive signals from the spinal cord, and sensory systems. The Cerebellum also coordinates voluptuary movement, balance and speech.
