Tournament Strategies




Don’t split systems between
teammates
Write down questions on your sheet
so you can answer them later
Bring a watch to time yourself at
stations.
Don’t panic if you don’t 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 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.
b
c
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
response?
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?

What are the
units of compact
bone?
What are the
large dark spots?
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
response?
• How does the cellular response to the release
of parathyroid hormone maintain homeostasis?

Which of the following
osteocytes?
Which of the following
Which of the following
do blood vessels and nerves run
are connecting tunnels between
house osteocytes?
house chondrcytes?

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?

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