resolutions each year. This shows how many of
these resolutions are maintained over time:
- past the first week: 75%

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-Th

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

• 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
the innate “fight or

• What is fear? What are you MOST afraid of?
• Introduction: Read the short article called “How Fear
Works.”
• On the back of the article, please answer the following
questions:
• 1. What are your top 2 fears?
• 2. Explain some of the events that take place when you
are experiencing this
fear! (Emotionally, physiologically, physically)

• Homework:
• Think about your own worst fear &
how you “react” to it.

Fundamentals
of the
Nervous System
The Master Controlling &
Communicating System
• 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 (voluntary) Nervous System (SNS) –
• Controls voluntary & involuntary skeletal muscle contractions
• Involuntary skeletal contraction – reflex
• Single motor neuron system between interneuron & effector
Subdivisions of Motor Division
(PNS)
• Autonomic (involuntary) 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/effectors
Subdivisions of
ANS
• Sympathetic
division –
▫ Fight or flight
• Parasympathetic
division –
▫ Regulates resting
functions
 Ex., digesting food
Sympathetic NS
• “ Fight or flight” response
Brain
• Release adrenaline & noradrenaline
• Increases heart rate & blood pressure
• Increases blood flow to skeletal muscles
SYMPATHETIC
CNS
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
CNS
• “Rest & digest” system
• Calms body to
conserve & maintain
energy
• Lowers heartbeat,
breathing rate, blood
pressure
Brain
PARASYMPATHETIC
Contracts pupil
Stimulates salivation
Spinal
cord
Constricts bronchi
Slows heartbeat
Stimulates activity
Stimulates gallbladder
Gallbladder
Contracts bladder
Stimulates erection
of sex organs

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

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?
