  1. Today in Human Anatomy... • Week #1 (1/7 – 1/10) • Warm Up – Tues, 1/7 & Wed, 1/8: • - Time is like Money • Have out: • Living Proof paper • Pick up: • Ch. 12 Tour • How Fear Works article • Paper towel assignment rubric • Reminder: • AT Still Field Trip payment DUE in Bookstore! Anatomy Fun Fact: 40 to 45% of American adult make one or more resolutions each year. This shows how many of these resolutions are maintained over time:- past the first week: 75%- past 2 weeks: 71%- after one month: 64%- after 6 months: 46% • Homework: • Ch. 12 Tour – Thurs, 1/9 & Fri, 1/10 • How Fear Works paper towel poster assignment – Tues, 1/14 • Agenda: • Nervous System Song & review of Reflex Arc • Discuss How Fear Works poster paper towel project • Finish Living Proof movie & writing assignment

  2. Classroom Policy Reminders & Keys to Success! • RESPECT…that’s it! • Use Schoolwires to access notes (PPTs), due dates & assignments! • If absent, you have 1 day for every day you are excused absent to make up work! • See Schoolwires or Agendas notebook/handouts bin for make-up work. • NO “late work” is accepted for credit! • Be to class on time & with required materials! • Be active in your own education…participate in class warm-ups, discussions & labs!!! • Use Office Hours if you need to make up work or get extra help… M-F before school & M & W at lunch

  3. New Year’s Resolution…perhaps? Timeis like Money $$$ • You can… • Well, you tell me… • Invest it… • Spend it… • Waste it… • How did YOUspend your time last semester? High school? • How can YOU choose to invest your time wisely so that you can be successful here & in your next step in life? • What behaviors or habits can YOU change or improve on so that YOU can be proud of the grades YOUearn & the person YOUare?

  4. Intro to the Nervous System • Nervous System Song • Fill in the lyrics as you listen to & watch the song video! • I will play it only twice!

  5. Reflex Arc Reflex Arc animation

  6. How Fear Works poster & paper towel project • Introduction: Read the short article called “How Fear Works.” • You will become re-familiarized with the common Reflex Arc that we have discussed already. • You will also learn more about the innate “fight or flight” reflex & how it works in response to fear.

  7. How Fear Works poster & paper towel project • Homework: • Think about your own worst fear & how you “react” to it. • Using the terminologies & anatomical & physiological concepts from the article, create a Fight-or-Flight poster (8.5 x 11) using “your fear” as the “stimulus”. • Needs to include: • Title – “_____(your name)’s Fight-or-Flight Reflex Arc” (3 pts) • Images of stimulus (identify your fear), sensory/afferent neuron, spinal cord, interneuron/association neuron, motor/efferent neuron, effector(s) (which muscles/reactions – skeletal/ smooth/cardiac) (6 pts) • Labels for all reflex arc parts listed above (6 pts) • Color (at least 4), creativity & originality (5 pts) • Poster attached to a paper towel roll (10 pts) 30 pts DUE: Tues, 1/14

  8. How Fear Works poster & paper towel project Mrs. Crozier’s Fight or Flight Reflex Arc Spinal cord Sensory/ My Fear - Wind Autonomic NS Sympathetic response: -Heart rate (cardiac) & breathing (smooth) increase -Gasp for air (smooth) -Scream (skeletal) -Tense up (skeletal) Motor/

  9. Living Proof • Based on the true story of the development of the breast cancer drug, Herceptin. • What kind of hurdles & difficulties did Dr. Slamon have to overcome to see his drug make it to market? • Why do you think the FDA puts such strict measures on the drug- testing process? • Are these measures ethical or not? • How does the Nervous System & psychology play a role in battling cancer?

  10. Today in Human Anatomy... • Week #1 (1/7 – 1/10) • Warm Up – Thurs, 1/9 & Fri, 1/10: - Pushing the Limits: Brain Power • Have out: • 1 piece of paper • Pick up: • Nervous System outline • Nervous System handouts • Turn in: • Ch. 12 Tour 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: • Begin Nervous System Unit • - Organization of the NS • Homework: • How Fear Works paper towel poster assignment – Tues, 1/14

  11. How Fear Works poster & paper towel project • Introduction: Read the short article called “How Fear Works.” • You will become re-familiarized with the common Reflex Arc that we have discussed already. • You will also learn more about the innate “fight or flight” reflex & how it works in response to fear.

  13. Pushing the Limits – Brain Power • Title your paper “Pushing the Limits: Brain Power Facts” paper & have out a pen/pencil. • Identify & explain at least 5 new concepts/ideas/facts you learn about the human brain/mind from the video. • Add these to your paper!

  14. Fundamentals of the Nervous System The Master Controlling & Communicating System Ch. 12-17

  15. Nervous System (Organization) Latin Roots • Neuri/a/o – related to the Nervous System • Re – again • Inter – between • Soma – body • Auto – self • Peri – around • Sym – together • Para – beside, next to • Path(o) – disease, suffering • -lemma – covering, sheath, membrane • Moto – movement • Ax(o) – axis • Pre – before • Post – after

  16. Central Nervous System(CNS) – Brain & spinal cord Peripheral Nervous System(PNS) – Made up of nerves that attach to CNS Cranial nerves Peripheral nerves Autonomic nerves Organization of the Nervous System

  17. Subdivisions of Motor Division (PNS) Somatic Nervous System (SNS) – Controls voluntary & involuntary skeletal musclecontractions Involuntary skeletal contraction – reflex Single neuron system

  18. Autonomic Nervous System (ANS) – Controls activity of smooth & cardiac muscles 2 neuron system 1st: from CNS to ganglion 2nd: from ganglion to effector Ganglion: collection of nerve cell bodies that act as a junction (“middleman”) between nerves originating from the CNS & nerves innervating target organs Subdivisions of Motor Division (PNS)

  19. Subdivisions of ANS Sympathetic division– Fight or flight Parasympathetic division– Regulates resting functions Ex., digesting food Color-code your picture of the NERVOUS SYSTEM!

  20. Sympathetic NS “ Fight or flight” response Release adrenaline & noradrenaline Increases heart rate & blood pressure Increases blood flow to skeletal muscles Inhibits digestive functions CNS SYMPATHETIC Brain Dilates pupil Stimulates salivation Salivary glands Relaxes bronchi Spinal cord Lungs Accelerates heartbeat Heart Inhibits activity Stomach Pancreas Stimulates glucose Liver Adrenal gland Secretion of adrenaline, nonadrenaline Kidney Relaxes bladder Sympathetic ganglia Stimulates ejaculation in male

  21. Parasympathetic NS “ Rest & digest” system Calms body to conserve & maintain energy Lowers heartbeat, breathing rate, blood pressure CNS PARASYMPATHETIC Brain Contracts pupil Stimulates salivation Constricts bronchi Spinal cord Slows heartbeat Stimulates activity Stimulates gallbladder Gallbladder Contracts bladder Stimulates erection of sex organs

  22. Summary of ANS differences Autonomic nervous system controls physiological arousal Sympathetic division (arousing) Parasympathetic division (calming) Pupils dilate EYES Pupils contract Decreases SALIVATION Increases Perspires SKIN Dries Increases RESPIRATION Decreases Accelerates HEART Slows Inhibits DIGESTION Activates Secrete stress hormones ADRENAL GLANDS Decrease secretion of stress hormones

  23. Checking for Understanding: Divisions of the NS 1-8: Fill in the blanks! What are the main regions and functions of the CNS & PNS? What is the main difference between the SNS & ANS? 1 complete the NS Concept MaP! be prepared to share your answers with the class! 2 3 4 5 7 8 6
