Today’s Lesson…
Muscular/Skeletal System
SOLS:
6.2 Knowledge of Body Systems
6.2b Interconnection of Body Systems
Target: Student will acknowledge that
the Skeletal & Muscular Systems rely on
one another in order to be productive.

• Bathroom
• Sharpen Pencils
The Framework: Your Skeleton
• Your Skeletal System provides the framework
for your body. The size and shape of your
body is based on the skeleton. Without our
skeleton, we would be a pile of mush on the
floor.
Therefore, the main purpose of the Skeletal
System is to shape and support your body.
How is the
skeletal system
like the
framework of a
house?
Jobs of the
Skeletal System
Continued…
Inside your body, you have
many parts that need to be
protected from the
environment.
Your brain , heart, and
lungs are sensitive organs
that need to be protected.
How does the Skeletal
System play a vital role in
protecting these organs?
Job #2
To protect the organs inside of the
body.
Example: Ribs protect Heart & Lungs
Cranium protects brain
Job #3
To work with the muscular system to
move the parts of your body.
Did You Know???
You were born with 350 bones!!!
By the time you are an adult you will only have 206
bones.
What Happened???
When you are young, your bones are soft. Over
time they harden and fuse together.
Why do you think you had soft bones as
an infant?
Two bones come together at
a Joint.
The
picture to
the left
shows the
rotator
cuff.
This joint
is
commonly
injured in
softball &
baseball
pitchers
A joint is
held
together by
a ligamentthis is a
tough yet
flexible
tissue that
connects
bone to
bone.
Bone Fractures
Greenstick, Open, Closed
• Greenstick Fracture – Flexible bone that splits
part way through
This type of fracture is common in
infants and toddlers.
Their bones are still
Soft, containing
cartilage.
Think of a young branch that is flexible and
green inside (hence the name greenstick
fracture). What happens when you try to break
the stick in half?
Closed Vs.
Open
Open Fracture: Also
known as a
Compound Fracture
•The broken ends of
the bone pierce the
skin.
Closed Fracture:
•Bone breaks completely, but
does not pierce skin
•More common than open
fracture
2 Types of Muscles
Voluntary Muscles• Also known as Skeletal Muscles
Involuntary Muscles• Also known as Smooth Muscles
Voluntary Muscle
• Also known as Skeletal Muscle
• Attached to bone
• Create movement
• Need lots of oxygen to keep working
• You control the movement therefore, the muscle
movement is voluntary
Involuntary Muscle
• Also known as smooth muscle
• Muscle works without thinking about it
• Example: Organs, skin, &
blood vessels
• Your Cardiac Muscle is involuntary.
How many cardiac muscles do you have?
Muscular System Notes Cont…
• Tendons connect muscles to bone
A popular tendon found in
your ankle is called the
Achilles Tendon.
Let’s Work Together
Question: How do muscles work
together (in pairs)?
Answer: One muscle contracts (shortens) while the
other muscle relaxes (lengthens).
Example: The bicep muscle pairs up
with the tricep
Partner: Ask a peer next to you to name
another muscle pair.
Tendons vs. Ligaments
