1. The Central Nervous System

2. Phineas Gage

3. The Central Nervous System
CNS - brain & spinal cord
PNS - nerves that connect spinal cord to rest of body

4. The Central Nervous System
brain & spinal cord surrounded by meninges (membrane), spinal fluid & bone (skull or vertebrae)
They cushion, nourish, & protect

5. Spinal Cord - located inside vertebrae of spine
contains interneurons that control motor reflexes
carries impulses between brain & PNS

6. Spinal Cord Grey Matter - nerve cell body & dendrites
White Matter - axons (usually myelinated)

7. In partners
Read the article & summarize
Be ready to teach another person the gist of the article
Be ready to learn from another person.

8. The Brain

9. Hind Brain
Three regions:
Medulla (oblongata)
Cerebellum
Pons

10. Hind Brain Medulla -involuntary behaviour control
eg. Heart, breathing, digestion

11. Hind Brain Cerebellum -voluntary muscle sensory signal receiver
(signals about movement and balance, by muscle & joint receptors)
Pons- neuron bundle that connects the cerebellum to the higher brain.
Brain

12. Cerebral Cortex (cerebrum)
Cerebrum controls the sensory & motor activities.
Four main sensory regions or lobes
- Frontal
- Parietal
- Occipital
- Temporal

13. Cerebral Cortex (cerebrum)
Frontal
-Thinking, planning, & personality

14. Cerebral Cortex (cerebrum)
Parietal
-sensory regions that register information about, touch, pain, temperature, & pressure

16. Cerebral Cortex (cerebrum)
Occipital
-sensory regions for vision.

17. Cerebral Cortex (cerebrum)
Temporal lobe
- regions for auditory sensory perception.

18. Construct a table about the parts and function of the:
- thalamus
- hypothalamus
- basal nuclei
- blood brain barrier
