1. Stress-strain curves
of vocal fold tissue rarely
show both nonlinearity and
stretch-release differences.
True
False
2. Biological tissues,
including those in the vocal
folds, are said to be linear;
this is evidenced by the "banana
shaped" curves in stress-strain
diagrams for different types
of vocal vold tissue.
True
False
3. Stress is a normalized
elongation.
True
False
4. Velocity is the rate
of change of displacement;
it is a vector quantity that
includes both speed (magnitude
of velocity) and direction.
True
False
5. Stress is an active
force; strain is the yielding
to a stress.
True
False
6. Hooke's law states that
stress is inversely proportional
to strain.
True
False
7. The innervation that
a muscle receives affects
the types of fibers that
develop in the muscle.
True
False
8. Actin and myosin are
two types of muscle fibers.
True
False
9. Muscle fibers which
have been stretched always
snap back to their unstretched
length at the same rate at
which they were stretched.
True
False
T. 10. Strain is the macroscopic
end product of many internal
dynamic interactions.
True
False
