The direction of the muscle's fasicles
The size of the muscle
The action of the muscle
The location of the muscle
All of the above may be used to name a muscle
A prime mover (agonist)
Is the muscle most responsible for a particular action
Is opposed by contraction of a synergist
Is destabilized by contraction of a fixator
Is assisted by contraction of an antagonist
All of the above are correct
Intramuscular injections are usually given
When medications must be absorbed more slowly than possible through oral administration
In the gluteus maximus of an adult
In the vastus lateralis of a child
Is the biceps brachii of an adolescent
When medications must be absorbed more quickly than possible through I.V administration
Fascicle arrangements
Are named based on their orientation with the tendon of the muscle
Affect the power of the muscles
Affect the range of motion of muscles
A and b are correct
A, b, and c are correct
A third class lever
Is the most common lever system in the human body
May be represented as FLE
Always produce a mechanical advantage
Favors force over speed
Favors force over range of motion
A first class lever
May be represented as FEL
Extends a bowed head on the vertebral column
Allows a ballerina to stand on her toes
Allows the forearm to flex on the arm
Is the least common lever system in the body
A lever
Is a rigid structure that moves about a fixed point
Provides mechanical advantage when a small effort can move a large load
That provides a mechanical advantage decreases the speed and distance needed to move a load
A and b are correct
A, b, and c are correct
Which of the following is true?

A and b are correct
A, b, and c are correct
Which of the following is true?
Muscles pull on bones; they do not push bones
The end of the muscle attached to the bone that moves least is the origin of that muscle
The end of the muscle attached to the bone that moves most is the insertion of the muscle
