1 Biology 3201 Unit 1 Timeline 1 Learning Objective # 1 Analyze the nervous system and explain its structure and dynamics 1. Explain the basic structure and function of the central nervous system. Include: (i) brain (ii) spinal cord 2. Explain how the nervous system is protected. Include (i) skull (ii) meninges (iii) cerebrospinal fluid 3. Explain the basic structure and function of the brain. Include: (i) cerebrum (ii) cerebellum (iii) medulla (iv) thalamus (v) hypothalamus (vi) midbrain (vii) pons (viii) corpus callosum 4. Describe the basic functions of a peripheral nervous system. Include: (i) sympathetic (ii) parasympathetic Learning Objective # 2 Explain how the nervous system helps to maintain homeostasis 1. Describe the structure of the typical neuron and explain the function of each part. Include: (i) dendrite (ii) cell body (iii) axon (iv) axon terminal (v) Schwann cells (myelin sheath and nodes of Ranvier) Learning Objective # 3 Identify the role of compounds to neuron function (oxygen, glucose, ATP, sodium ions) , , , 395 and 404, , , , 402 Learning Objective # 4

2 Analyze homeostatic phenomena to identify the feedback mechanisms involved Specific 1. Describe a reflex arc Learning Objective # 5 - Core Lab # 1 Perform an experiment to investigate and collect data on the nervous system (reflexes) and identify specific variables involved Compile and organize data, using appropriate formats and data treatments to facilitate interpretation of the data Identify and explain sources of error and uncertainty in measurement and express results from this nervous system activity in a form that acknowledges the degree of uncertainty Learning Objective # 6 Describe disorders linked to the, nervous system and their effecl on homeostasis of the system and the organism as a whole. Include: i. Multiple Sclerosis Alzheimer's Disease i Parkinson's Disease Meningitis v. Huntington's Disease Learning Objective # 7 Analyze why and how technologies related to the treatment of nervous system disorders were developed and improved over time Describe the technologies (i) MRI (ii) EEG (iii) CAT Scan 2. Describe the methods used to treat stroke and spinal cord injury

Include: (i) anaesthetics (ii) prescription drugs (iii) illegal drugs (iv) legalized drugs (alcohol, nicotine, caffeine) Learning Objective # 9 Distinguish between questions that can be answered by science and those that cannot, and between problems that can be solved by technology and those that cannot Appendix C Appendix C 3 1. Debate the merits of using drugs for treatments of nervous disorders against the long-term side effects Learning Objective # 10 Propose courses of action on social issues related to science and technology, taking into account an array of perspectives, including that of sustainability. Appendix C 1. Debate the legalization of certain drugs such as marijuana for medicinal purposes Learning Objective # 11 Explain how the eye as a sense organ helps maintain homeostasis 1. Describe the general structure and function of the eye. Include: (i) lens (ii) iris (iii) retina (iv) cornea (v) choroid layer (vi) fovea (vii) rods (viii) cones (ix) pupil (x) blind spot 2. Trace the path of light through the eye and explain how the amount of light entering the eye is regulated Learning Objective # 12 Analyze and describe examples of disorders of the eye and where
