300 How does the nervous system maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning and emotional response, and activate muscles and glands?
300 
300 What are the divisions of the nervous system and their components?
300 
300 How does the structure of the neuron relate to its role in nerve transmission?
300 How are reflex arcs used to maintain homeostasis?
300 How do nerve impulses travel down a neuron and how is the nerve impulse transmitted to other cells?
300 What are the responsibilities of major structures of the brain?
300 What occurs in the brain during the following devlopemental stages: newborn, adolescence and old age? 
300 What are the causes and consquences of various cerebral and spinal pathologies?
300 
400 1. The neuron, nerve impulse, and synapse
400 2. The central nervous system: brain and spinal cord
400 3. The peripheral nervous system
400 4.  The senses
400 5. The effects of phychoactive drugs on the brain, addiction
400 6. The adolescent brain, the aging brain
400 
500 Students will develop the ability to:
500 1. Describe a nerve and explain its job
500 2. Locate and describe the role of the following parts of a neuron: dendrite, axon, cell body, myelin sheath, node of Ranvier, axon terminal
500 3. Sequence the event and explain the process of a nerve impulse, including a description of the ion distributions and membrane potential of a neuron at rest, with an action potential, and during refractory period
500 4. Explain the process of a synaptic transmission of a nerve impulse, including the role of neurotransmitters
500 5. Describe the function of the central nervous system: brain and spinal cord
500 6. Describe the function and locate major parts of the brain: olfactory bulb, corpus collosum, cerebellum, medulla oblongat, thalamus, hypthalamus, cerebrum (cerebral cortex: occipital, frontal, parietal, temporal lobes)
500 7. Distinguish between white matter and gray matter
500 8. Sequence the events of a spinal reflex arc and describe its importance
500 9. Explain the reasoning for teenage risk taking and angst
500 10. Explain how to prevent memory loss and aging of the brain
500 11. Explain how the brain and spinal cord are protected by bone, meninges, cerebrospinal fluid
500 12. Organize the divisions of the nervous system and list the role and organs of each
500 13. Locate and explain the function and major structure of the eye and relate these structures to common eye disorders
500 14. Locate and explain the function of the major structure of the ear 
500 15. Explain how the following psychoactive drugs interfere with normal synaptic transmission and produce reward: cocaine, alcohol, ecstasy, caffeine
500 16. Describe the relationship between drug abuse, tolerance, and drug addiction
500 17. Explain why drug addiction is considered a disease and how it is treated 
600 1. Diagrams and models of brain, spinal cord, eye, and ear
