1. Chapter 8.7: Nervous System

2. Limbic System Establishes emotion and behavior Links conscious with autonomic Long-term memory storage and retrieval Makes you “want” to do things Rage, fear, sexual arousal

3. Diencephalon Epithalamus Contains pineal gland Secretes melatonin Regulates day/night cycles

4. Figure 8.24a

5. Diencephalon cont… Thalamus Coordination of voluntary and involuntary motor commands

6. Figure 8.24a

7. Diencephalon cont… Hypothalamus Subconscious control of skeletal muscle associated with rage, pleasure, pain and sexual arousal Adjusts autonomic centers Heart rate, blood pressure, respiration and digestion Coordinates nervous and endocrine system Secretes hormones

8. Hypothalamus cont… Produces feelings of hunger and thirst Regulates body temperature Coordinates daily cycles

10. Midbrain Process visual and auditory sensations Control reflex movement of eyes, head and neck Contains reticular formation Controls sleep cycles Maintains muscle tone and posture Damage here = Parkinson’s Disease Difficulty starting voluntary movements

14. The Cerebellum Maintains balance Permanently damaged by trauma/stroke Temporarily damaged by drugs/alcohol Produces ataxia Disturbance in balance

16. Medulla Oblongata Connects brain with spinal cord Cardiovascular centers Adjust heart rate Adjust cardiac contraction strength Flow of blood Respiratory centers Respiratory movements
