Transcript and Presenter's Notes

Title: Anatomy (B) Anatomy and Physiology (C)

Anatomy (B)Anatomy and Physiology (C)
  • Mangala Iyengar
  • 10/3/09
  • Science Olympiad Coaches Institute

The Event
  • Covers anatomy, physiology, and pathology of the
    skeletal and muscular systems (and endocrine, for
    Division C)
  • Includes process skills and memorization
  • 1 2-sided page of notes allowed

Test Format
  • Timed Stations
  • Case Studies
  • Data Analysis
  • Passage Analysis (Division C)

Study Focuses
  • Critical Thinking and Logical Reasoning
  • Integration of Systems the big picture
  • Pathology as a window to physiology
  • Speed
  • Memorization is important and necessary but it
    isnt enough.

  • Campbells Biology

Tournament Strategies
  • Dont split systems between teammates
  • Write down questions on your sheet so you can
    answer them later
  • Bring a watch to time yourself at stations.
  • Dont panic if you dont know the answer off the
    bat try to reason your way through

Concept Review
Mock Event Part 1
  • Directions will be on the projector screen
    follow Anatomy or Health Science instructions as
  • 1st portion Anatomy Stations, Health Case
    Studies. Stations are in this power point case
    studies is further back in the notebook.

Anatomy Station 1
  • 1. Match each picture to the type of muscle
    tissue it represents

2. What purpose do the intercalated discs serve
in cardiac muscle?

Anatomy Station 2
  • Parathyroid Hormone (also known as parathormone)
    is a hormone released from the parathyroid glands
    that regulates the levels of calcium in the
    blood. When calcium concentrations in the blood
    get low, parathyroid hormone sends signals to a
    particular type of bone cell.
  • What do osteoclasts do?
  • What do osteoblasts do?
  • Which of the cells do you think are receiving the
    signal from parathyroid hormone?
  • What do you think these cells are doing in

Anatomy Station 3
  • What happens to cardiac muscle when a person
    performs moderate aerobic exercise over a period
    of several months?
  • Weightlifters increase their muscle size over
    time. Does this result from an increase in the
    number of muscle cells or an increase in the
    number of muscle fibers?

Anatomy Station 4
  1. What are the units of compact bone?
  2. What are the large dark spots?
  3. What are the small dark spots?

Mock Event Part 2
  • Health Science stations will be up on the
    projector Anatomy will be doing case studies

Health Science Station 1
  • Under what conditions does parathyroid hormone
    send messages to cells in the bone?
  • What type of bone cell is most likely to receive
    the signal from parathyroid hormone?
  • What do you think these cells are doing in
  • How does the cellular response to the release of
    parathyroid hormone maintain homeostasis?

Health Science Station 2
  • Which of the following do blood vessels and
    nerves run through in bone?
  • Which of the following are connecting tunnels
    between osteocytes?
  • Which of the following house osteocytes?
  • Which of the following house chondrcytes?
  • Word bank for questions 1-4 Lacunae
  • Colliculi
  • Osteal canals
  • Central Canals
  • Canaliculi
  • Lacunae
  • 5. Open ended Would it hurt less to pierce your
    belly button or your ears? Why?

Health Science Station 3
  • In the disease called Amyotrophic Lateral
    Sclerosis, motor neurons die off and stop sending
    signals to muscles. What is the most likely thing
    that will happen to muscles as a result?
  • What is the major event that allows a neural
    signal from a motor neuron to pass to muscles?

Health Science Station 4
  1. What is wrong with this person?
  2. Circle the part of the X-ray that allowed you to
    diagnose the person
  3. List 3 symptoms that this patient might be
  4. Name one activity that this person should
    probably avoid.
