The Human Brain The brain is part of the Central nervous system

The nervous system The nervous system is made of millions of neurons. A neuron is a nerve cell Axon is the cell body Dendrites receive incoming messages

The brain The brain is the control center for all incoming nerve impulses. The brain is broken into 3 parts. The cerebrum, cerebellum and medulla oblengota

Cerebrum The Cerebrum has 4 parts Frontal lobe Parietal lobe Occipital lobe Temporal lobe

The Cerebrum Controls Consciousness high mental processing and voluntary movements All four parts control different features of the brain. Left brain is for speech and language Right Brain is for spatial relationships, music, art and emotions

Cerebellum The cerebellum is the ball shaped organ at the cerebrum base. It is responsible for balance and complex muscle movements

Brain Stem The medulla is also called the brain stem. Responsibilities include: Breathing, swallowing, digestion, and actions of the heart and blood vessels. Here is where all of the nerves of the spinal cord connect to the brain
