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

New Year’s Resolution…perhaps?Time is like Money $$$•You can…

▫ Well, you tell me…▫ Invest it…▫ Spend it…▫ Waste it…

• How did YOU spend 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 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)

Mrs. Crozier’s Fight or Flight Reflex Arc

My Fear - Wind

Sensory/

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 drug- testing 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

Have out:1 piece of paper

Pick up:Nervous System outlineNervous System handouts

Turn in:Ch. 12 Tour

Agenda:1. Begin Nervous System Unit

- Organization of the NS

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.

•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!

Pushing the Limits – Brain Power

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

• 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)

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

• Inhibits digestive functions

CNS

Brain

Spinalcord

SYMPATHETIC

Dilates pupil

Stimulates salivation

Relaxes bronchi

Accelerates heartbeat

Inhibits activity

Stimulates glucose

Secretion of adrenaline,nonadrenaline

Relaxes bladder

Stimulates ejaculationin male

Sympatheticganglia

Heart

Stomach

Pancreas

Liver

Adrenalgland

Kidney

Parasympathetic NS

•“ Rest & digest” system

•Calms body to conserve & maintain energy

•Lowers heartbeat, breathing rate, blood pressure

CNS

Brain

PARASYMPATHETIC

Spinalcord

Stimulates salivation

Constricts bronchi

Slows heartbeat

Stimulates activity

Contracts bladder

Stimulates erectionof sex organs

Stimulates gallbladder
