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
