Creep is:
-A characteristic of elastic material where changes of deformation is measured under
constant load
-A characteristic of viscoelastic material where changes of deformation is measured
under constant load
-A characteristic of viscoelastic material where changes of stress is measured under
constant deformation
-A characteristic of elastic material where changes of stress is measured under
constant deformation - Answer A characteristic of viscoelastic material where changes
of deformation is measured under constant load
Which one of the following joints is considered amphiarthrodial joint?
-Symphysis of pubis
-Elbow joint
-Hip joint
-carpometacarpal joint of the thumb - Answer Symphysis of pubis
While standing upright, one attempts to bend and reach the great toe with tip of his
hands while the knees are fully extended. He notices a pain in his hamstring. This is
most likely due to:
-Passive insufficiency of hamstring
-Passive insufficiency of quadriceps
-Active insufficiency of hamstring
-Active insufficiency of quadriceps - Answer Passive insufficiency of hamstring
Anisotropic characteristics of bone meant that it has:
-Different mechanical property when load is applied at different direction
-Different mechanical property when the amount of load changes
-Has only one single young's modulus (modulus of elasticity)
, -Does not have a particular young's modulus due to changes in mechanical properties
over time - Answer Different mechanical property when load is applied at different
direction
A therapist assesses her patient's hamstring strength in the sitting position and
standing positions. The therapist finds that the patient's strength is significantly better
in sitting when compared to the standing position. Which of the following is the MOST
likely reason for the diminished end range knee flexion strength in standing?
-Active insufficiency of the hamstrings
-Active insufficiency of the Quadriceps
-Passive insufficiency of the hamstrings
-Passive insufficiency of the Quadriceps - Answer Active insufficiency of the hamstrings
Which one of the following has the greatest impact on the amount of force that muscle
can generate?
-The number of muscle fibers in parallel
-The number of muscle fibers in series
-The percentage of fast twitch muscle fibers within the muscle
-Overall length of muscle-tendon complex - Answer The number of muscle fibers in
parallel
A biomechanical model of muscle consists of a parallel elastic components, series of
elastic components and contractile elements. What anatomical structure represents
parallel elastic components
-Endomysium and perimysium
-Actin and myosin
-Tendon
-Anatomical cross sectional area - Answer Endomysium and perimysium
Permeability of cartilage is:
-The ability for the fluid to transmit through
-The ability to tolerate stress
-The ability to tolerate strain
-The ability to respond differently to different direction of load - Answer The ability for
the fluid to transmit through
