CHAPTER 3.1 (part 2) and 3.2 READING GUIDE: Name: ______________________________ 3.1 → Communication in the Nervous System (part 2) 11. Discuss the process of a neurotransmitter binding to a receptor site on a postsynaptic neuron, including why it is so specialized. 12. What are some key characteristics of acetylcholine (Ach)? What is its relationship with Alzheimer’s disease? 13. Explain what is happening when nicotine acts as an agonist for Ach. Do the same for the drug curare acting as an antagonist. What is the result? 14. Use the entire Monoamines section to discuss the following three neurotransmitters (be sure to include specific diseases/conditions associated with each): Picture of woman, needle and hands on p. 87: Is botox acting as an agonist or antagonist? ______________________ Dopamine → Serotonin → Norepinephrine → 15. Summarize the relevant information for the following transmitters: GABA → Table 3.1: Write the disorder associated with each of the following: Ach: ____________________________ DA (too little): ____________________ DA (too much): ___________________ NE/Serotonin: ____________________ GABA: __________________________ Glutamate → Concept Check 3.2: 1) ______ 2) ______ 3) ______ 4) ______ 5) ______ Endorphins → 3.2 → Organization of the Nervous System 1. Briefly describe the important information for each of the following (if there is not much more than a definition, summarize/paraphrase/reword it, since you’ll be writing the definition in your vocab.): Figure 3.6: How many parts make up each of the following? The NS: _____The CNS: _____ The PNS: _____ SNS: _____ ANS: _____ The peripheral nervous system → The somatic nervous system → Afferent nerve fibers → Efferent nerve fibers → The autonomic nervous system (include Cannon’s term) → The sympathetic division → The parasympathetic division → The central nervous system → The spinal cord → The brain → Figure 3.8 The ANS: Parasympathetic division = ______________________ Pupils → ______________ Respiration/Heart rate → _____________________ Sympathetic division = ______________________ Pupils → ______________ Respiration/Heart rate → ______________________
