2. Facts About the Human Brain
It’s the center of the nervous.
The brain is located in the head and protected by the skull.
It’s average weight is about grams.
It’s about 75% water.
The brain consists of about 100 billion neurons.

3. Brain Lobes & Functions
Right and Left
Hemispheres
Brain Stem
Cerebellum
Frontal Lobe
Temporal Lobe
Parietal Lobe
Occipital Lobe

4. Brain Stem Connected to the spinal cord
Controls processes basic for survival, such as heart rate, breathing, digestion, and sleep
Main route of communication throughout the body

5. Cerebellum Second largest part of the brain
Controls posture and balance
Has a role in higher cognitive processes

6. Frontal Lobe Behind the forehead.
Needed for planning, memory search, motor control, and reasoning & speech.
Includes the Motor Strip: controls fine movements and is organized by body part.

7. Temporal Lobe Below temples, in front of ears.
Needed for visual memory and hearing.

8. Parietal Lobe Upper-rear of the head
Registering spatial location, attention, and motor control.
Includes the Somatosensory Strip: registers sensation on the body and is organized by body part.

9. Near the back of the head. Needed for vision.
Occipital Lobe
Near the back of the head.
Needed for vision.
