Moving the Body
Objective: SWBAT explain
how the body moves
WARM UP:
1. Write the definition of
the muscular system in
your notebook. (Look
up the definition in
the back of the yellow
textbook)
Muscular System
• The muscles of the body that, together with
the skeletal system, functions to produce
movement
• Gives us strength
Remind me…
• What is the function of the SKELETAL SYSTEM?
• What do we call the place where two or more
bones meet?
Joints
• Immovable (fixed) joints: joint that does not
move
Example: joints in between the bones of your
skull
• Movable Joints: joints that move
Example: finger joints
Movement
• Can your bones move on their own?
Connective Tissues
• Tendons: connect MUSCLES to BONES
• Ligaments: Connect BONES to BONES
• Cartilage: Strong and flexible connective
tissue that covers the ends of bones at a joint.
It also gives shape and support to other parts
of the body, like ears, nose and the windpipe.
Supporting the Support System!
• What is the function of the MUSCULAR
SYSTEM?
• What different types of muscles?

Are All Muscles the Same?
• Three types: Cardiac, Smooth, and Skeletal

Tear out a piece of notebook paper
Fold “hamburger” style, cut down the fold
Cut one paper so that it forms 2 flaps
Cut the other paper so that it forms 3 flaps
Foldable
• Tape or glue the flap on your notebook
• Label the two flaps
Involuntary
Muscles
Voluntary
Muscles
Tape
Muscle Notes!
• Muscles are divided into two main categories
Involuntary: Muscles that can contract without
you actively making them
Example: pupils in your eye
Muscle Notes!
• Voluntary: muscles that contract when you
make them do so
Example: skeletal muscles
Foldable
• Tape or glue the other flap on your page or
back of page
Tape
• Label the three flaps
Cardiac
Muscle
Smooth
Muscle
Skeletal
Muscle
Three types of Muscles
• Cardiac Muscle:
-found only in the heart
-makes the heart beat
• Would this be a voluntary or involuntary
muscle????
Three types of Muscles
• Smooth Muscle:
-not banded, it’s smooth
-inside many organs like the stomach
-mostly involuntary
Three types of Muscles
• Skeletal Muscle:
- “striated” or banded
-attaches to bones
-moves bones
• Would this be a voluntary or involuntary
muscle????
Add Drawings
• Page B 24 and B 25 in big yellow textbook
• DRAW cardiac, smooth, and skeletal muscle
next to the definitions in your foldable
