What are the main regions/ organs & functions of the CNS & PNS? 10. What is the main difference between the SNS & ANS? 3 5 6 4 7 8 Week #1 (1/7 – 1/8) Warm Up – Fri, 1/8: - Ever wonder how…??? Anatomy Fun Fact: There are millions of nerve cells in the human body. This number even exceeds the number of stars in the Milky Way. Agenda: 1. Gruesome Medical Discoveries & Procedures video & writing assignment Have out: A piece of paper & label it “Gruesome Medical Discoveries & Procedures response” Homework: 1. How Fear Works poster project – Tues, 1/12 Ever wonder how… • we know about the brain, its regions, parts & functions? • we have been able to diagnose problems within the nervous system? • the first medical procedures investigating the nervous system occurred? Gruesome medical discoveries & procedures (~45 mins) Medical Procedures & the Brain • How do we know about the brain, its regions, parts & functions? • How have we been able to diagnose problems within the nervous system? • Where & how did the first medical procedures investigating the nervous system occur?
