Bio 348 Muscle Questions with Correct Answers
In the lateral view, identify fibularis (peroneus) longus and fibularis (peroneus) brevis.
Why do these two muscles belong in the posterior compartment if they are located
laterally?
because they are divisions of sciatic nerve and they are involved in plantar flexion and
eversion
Which tendon do these two muscles insert? (gastroc and soleus)
achilles tendon
Identify the flexor digitorum longus Is this located deep or superficial to the soleus?
superficial
When a stimulus to a skeletal muscle is sufficient to maintain muscle tone, but the
distance between the ____________ and the ____________ decreases, the muscle is
performing an isotonic / isometric (circle one) contraction.
origin and insertion, isotonic
When the force of muscle contraction increases, but the length of the muscle does not
change, the muscle is said to be in an isotonic / isometric (circle one) contraction.
isometric

the _____________ can determine the _____________ the muscle is capable of

, The capacity of any machine, including a muscle acting on a bone, to perform work is
related to the __________ it can exert and the ___________ over which movement takes
place; represented by the following equation: w=f*d
