Todays Stations:
• Independent Station: Correct Sub HW. Then
work on Musculoskeletal Questions
• Group Station: Make Flashcards for new
terms. When you finish, Use Powerpoint on
website for pictures to draw on flashcards
• Direct Instruction: Teacher Check ins. Work on
other 2 stations work
Group Station Vocab List

1. Did you finish all of your HW due today?
-How were you able to get it finished
-Why weren’t you able to get it finished
2. How was your behavior with the sub. Rank yourself 1
– 10 and explain why you gave yourself that score
3. How was the class behavior with the sub. Rank the
class 1-10 and explain why you gave the class that
score
4. How do you feel about the new material about
muscles? Why?

Wednesday, March 13th, 2013
Your Learning Goal:
Students will be able to identify different types of joints
and explain how muscles make your skeleton move
Standard: 5c: Students know how bones and muscles
work together to provide structural framework for
movement.

Review Questions
• Skeletal muscle?
Sub Review: Types of muscle
• Skeletal Muscle: Voluntary muscles that pull on bones to help you
move. These muscles allow you to move!
– Striated (striped) muscles without branches. Skeletal muscles contract
to pull on bones to move the bones. Forms bundles.
• Smooth Muscle: Involuntary muscles that squeeze food through
your digestive system. These muscles help you get nutrients!
– Muscles in sheets that contract and squeeze food through the digestive
system
• Cardiac Muscle: Involuntary muscle in the heart that pumps blood
through the body. This muscle pumps your blood!
– Striated muscles that have branches. Cardiac muscles contract to pump
blood out of the heart and into the arteries and relaxes to let blood into
the heart.
Sub Review: Types of muscle
• Voluntary Muscle: Muscles that you control with your brain.
You think and then you move.
– Includes Skeletal Muscles
• Involuntary Muscles: Muscles you can not control. These
muscles work in your body without you thinking about it.
They just work!
– Includes Cardiac Muscle and Smooth Muscle

What is our muscular
system?
• Muscular system: Muscles
that provide movement for
the body.
– The muscular system is made
up of skeletal muscles.
– Muscles work when the brain
sends the muscle a message.
The message tells the muscle
to contract (shorten). This
pulls on the bone and causes
movement.
Levels of Organization Review
1. Atoms are the basic unit of matter.
2. Atoms work together to make molecules.
2.5. Organelles (not pictured) like mitochondria and the nucleus are made out
of molecules working together.
3. Organelles work together to make a cell. Cells are the basic unit of life
4. The SAME cells work together to make a tissues

Examples of tissues: Muscle tissue, nervous tissue, connective tissue,
epithelial tissue
Different tissues work together to make organs
Organs work together to make an organ system
Organ systems work together to make an organism
Muscles are organs made out of
different tissues
Muscles are organs!
• There are 600 different muscles in
your body
• Each different muscle is an organ.
• Each muscles is made out of:
– muscle tissue: The bundles of muscle
cells that contract to pull on your
bone
– Nervous tissue: Tissue made out of
cells that send messages from the
brain to your muscle to tell it to
contract
– Connective tissue: The blood that
delivers the sugar and oxygen so
your muscles can work
– Epithelial tissue: The cells that cover
your muscles to protect them
Muscular system is an organ system
• The muscular system is all the skeletal muscles
working together in your body to make you
move
• Each muscle is an organ
• Organ systems are made out of organs
working together
• The muscular system is made out of muscles
(organs) working together.
Class Focus
• We are going to focus on skeletal muscles.
• We will talk about smooth muscle and cardiac
muscle when cover the digestive and
circulatory systems.
What is the Skeletal System
• Skeletal system- the
framework of bones and
other tissues that supports
the body
– Gives the body structure
– Supports the weight of the
body
– Protects your internal organs
(rib cage!)
– Bone marrow inside the bone
makes red blood cells
• Our bodies are made up of
206 bones.
• Babies have more than 206
bones because their bones
have not fused (grown)
together all the way

What is the Musculoskeletal System
• Musculoskeletal system: The
organ system made up of
muscles and bones working
together
• Organ parts:
–

–
–
Muscles
Bones
Joints
Tendons
Ligaments
• Main jobs:
Muscular system + Skeletal system
– Provide Support for the body
– Provides structural framework for
movement
What are joints?
• Joints-the place where two or more bones
meet.
– Ex: the elbow joint or knee joint.
Movement happens around joints.
Pictures of different joints in the body
What are tendons
• Tendons are fibrous connective tissues that
connect muscles to bone.
How does skeletal muscles work
• Muscles are connected to bone
• When muscles contract, they shorten and pull
on the tendon connecting it to the bone.
• Muscles work in antagonist pairs
What are antagonistic pairs
• Antagonistic Pair: One muscle and contracts
and pulls while the other muscle relaxes and
extends.
– Flexor: A muscle that pulls a limb into the body:
BENDING
– Extensor: A muscle that extends a limb away from
the body: EXTENDING
How do muscles work in Curls #getbig
– The bicep contracts and pulls the forearm bone
into the body and curls the arm.
– The triceps relaxes and lets the forearm bend into
the body.
How do muscles work during throw
ins!
– The triceps contracts and pulls the forearm bone
away from body and extends the arm.
– The bicep relaxes and lets the forearm extend
Tomorrows lesson: Do not continue
What are GLIDING/SLIDING JOINT
• Gliding joints are found in
our wrists, ankles, and
backbone.
• Gliding joints do what they
say: they glide past one
another, and help us move
those body parts.

What are BALL AND SOCKET
Ball and Socket Joints work look like a
ball in a socket. They allow for 360
degree rotation (the most rotation of all
the joints). The ball and socket joints in
our body are our shoulders and hips.
They work like joysticks on your video
game controllers
Examples of Ball and socket joints
What are HINGE JOINTs
• Hinge joints move up
and down in one
direction, like a door
opening and closing.
This type of joint can
be found in our
fingers, elbows, and
knees.
A hinge joint allows extension and flexing of an appendage
Hinge Joints Example
They work just like a
door hinge.
What are PIVOT JOINT
• Pivot joints: one bone turns in
the ring of another
• Joint between 1st and 2nd neck
vertebrae. And the joint
connecting the radius and ulna
of the for arm
Questions
• What is a joint?
• Which joint gives you the most mobility?
• Which type of joint do you have in your
fingers?
• Which type of joint only moves in 2
directions?
• Which joint functions like:
