What is the sliding filament theory?
The theory of how a muscle contracts.
The theory of how people use their muscles.
The theory of how organs slide around in the body
The theory of how much scientists know about muscles
True or False
There are three different types of muscle tissue; skeletal muscle, smooth muscle and cardiac muscle.
True
False
True or False
The myosin head pulls the actin toward the M line to shorten the sarcomere creating a muscle contraction. This is known as a power stroke.
True
