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


1
Anatomy (B)Anatomy and Physiology (C)
  • Mangala Iyengar
  • 10/3/09
  • Science Olympiad Coaches Institute

2
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

3
Test Format
  • Timed Stations
  • Case Studies
  • Data Analysis
  • Passage Analysis (Division C)

4
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.

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
8
Mock Event Part 1
  • Directions will be on the projector screen
    follow Anatomy or Health Science instructions as
    appropriate.
  • 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

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

10
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
    response?

11
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?

12
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?

13
Mock Event Part 2
  • Health Science stations will be up on the
    projector Anatomy will be doing case studies

14
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
    response?
  • How does the cellular response to the release of
    parathyroid hormone maintain homeostasis?

15
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?

16
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?

17
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
    experiencing.
  4. Name one activity that this person should
    probably avoid.
