Antagonistic Pairs
Skeletal muscles work in pairs
As one muscle contracts the other relaxes
•
•
Muscles are attached to bones by
_______________
Tendons
Muscles—tendon—bone
Nervous
All movement is coordinated by the _________
system
• What other systems do you think
is important to the skeletal and
muscular systems?
Nervous System to coordinate movement
Circulatory System to deliver nutrients and oxygen for
energy and take away wastes
Review – Energy
•
•
Energy can not be created or
destroyed
Energy can be converted (transformed
to another form ex. Electrical to Heat
in a clothes iron
