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 YOU earn & the person YOU are?

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!

Reflex Arc animation

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.

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

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

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 drugtesting process? ▫ Are these measures ethical or not? ▫ How does the Nervous System & psychology play a role in battling cancer?

Week #1 (1/7 – 1/10) Warm Up – Thurs, 1/9 & Fri, 1/10: - Pushing the Limits: Brain Power 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. Begin Nervous System Unit - Organization of the NS Have out: Ø 1 piece of paper Pick up: ØNervous System outline ØNervous System handouts Turn in: ØCh. 12 Tour Homework: 1.

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!

Fundamentals of the Nervous System The Master Controlling & Communicating System

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

• 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

Subdivisions of Motor Division (PNS) • Somatic Nervous System (SNS) – ▫ Controls voluntary & involuntary skeletal muscle contractions ▫ Involuntary skeletal contraction – reflex ▫ Single neuron system

Subdivisions of Motor Division (PNS) • Autonomic Nervous System (ANS) – ▫ Controls activity of smooth & cardiac muscles ▫ 2 neuron system 1 st: from CNS to ganglion 2 nd: 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 ANS • Sympathetic division – ▫ Fight or flight • Parasympathetic division – ▫ Regulates resting functions Ex. , digesting food

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

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

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