Muscular/Skeletal SystemSOLS:6.2 Knowledge of Body Systems6.2b Interconnection of Body SystemsTarget: Student will acknowledge that the
Skeletal & Muscular Systems rely on one another in order to be productive.

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 #2To protect the organs inside of the body.Example: Ribs protect Heart & Lungs
Cranium protects brainJob #3To 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 ligament- this is a tough yet flexible tissue that connects bone to bone.
Bone FracturesGreenstick, Open, Closed
• Greenstick Fracture – Flexible bone that splits part way through
This type of fracture is common in infants and toddlers. Their bones are stillSoft, containingcartilage.
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. OpenOpen 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.
