1. Nervous System By Allison Merritt, Tyler Tunell

2. What is the Nervous System? Made of Neurons Controls body functions and processes Divided into CNS, and PNS

3. Neurons A specialized cell in the nervous system Carries neural impulses through a complex system of neurons 3 types: Sensory, Motor, and Interneuron's

4. Neurons

5. Brain Structure/ Function Forebrain –5 main regions: Thalamus, Hypothalamus, Amygdala, Hippocampus, and Cerebral Cortex Hindbrain – 3 areas: Medulla, Cerebellum, and Pons Midbrain

6. Brain Structure/ Function Central Nervous System Peripheral Nervous System

7. Brain Structure/ Function

8. Anatomy and Function of Spinal Cord Link between PNS and brain White matter Gray matter Dorsal root Ventral root Reflexes Intervertabral Disk Disease

9. Anatomy and Function of Spinal Cord

10. Sensory Somatic and Autonomic Nervous System Somatic Autonomic Plexus Sympathetic Parasympathetic Drugs, and medications Receptors

11. Clinical Practice Aids in determining location of a defect in nervous system Tests: – Menace response – Pupillary light reflex – Classic reflex – Gag reflex – hearing

12. Anesthetics and diseases block sodium ions across membrane Extremely useful Surgical purposes Ataxia-uncontrollable movement Atrophy-muscles shrink Listeriosis-infection that affects the brain
