Most muscles cross at least one_________
a) tendon
b) joint
c) bone
d) ligament
e) body plane
b) Joints
The attachment of a muscle's tendon to the
stationary bone is called the _____; the attachment
of the muscle's other tendon to the movable bone
is called the _____.
,a) origin, action
b) insertion, action
c) origin, insertion

A lever is acted on at two different points by two
different forces which are called the___________
a) fulcrum and resistance.
b) leverage and load.
c) lever and resistance.
d) effort and load.
e) lever and effort.
d) effort and load
Motion will occur in a muscle when the _____
supplied exceeds the _____.
a) effort, load
b) resistance, lever
c) load, effort
d) load, resistance
e) lever, effort
a) effort and load
With reference to the effort and load , describe the
main difference between lever operating with a
mechanical advantage versus lever operating at
mechanical disadvantage
,Mechanical advantage occurs when the load is
placed closer to the fulcrum, thus requiring less
effort in the movement of the load.
Mechanical disadvantage occurs when the load is
placed farther from the fulcrum. This results in
more effort to be exerted to move the load.
Briefly describe the three categories of levers
based on the position of their fulcrum. Give an
example of each type of lever and state whether
the lever works at a mechanical advantage,
disadvantage, or both.
First class lever: scissors, and they can function at
a mechanical advantage or a mechanical
disadvantage
Second class: Wheel Barrow is a second-class lever
system, and it functions at a mechanical
advantage.
third class: Forceps (tweezers) function as a third
class lever, and they function at a mechanical
disadvantage.

arrangement of muscle fascicles?
a) pennate
b) triangular

d) parallel
e) fusiform
c) Oval
, This type of fascicle arrangement has the fascicles
spread over a broad area and converges at a thick
central tendon.
a) triangular
b) pennate
c) circular
d) fusiform
e) multipennate
a) Triangular
The muscle that serves as the "prime mover"
during a movement is called the_________.
a) antagonist.
b) agonist.
c) synergist.
d) asynergist.
e) fixator.
b) Agonist
This type of muscle works by stabilizing the origin
of the agonist so that it can act more efficiently.
a) synergist
b) agonist
c) antagonist
d) fixator
e) secondary mover
d) Fixator
