The stretch reflex is enhanced in response to activation of
the Golgi tendon organ.
alpha motoneurons.
gamma motoneurons.
lower motoneurons. ......ANSWER........gamma motoneurons.
In regards to the relationship between resting muscle fiber
length and tension generated, maximal tension is generated
when the thick and thin filaments slightly overlap.
,age 2 of 41
maximal tension is generated when the thick and thin filaments
do not overlap.
maximal tension is generated when the thick and thin filaments
greatly overlap.
the amount of overlap is unimportant in determining maximal
tension. ......ANSWER........maximal tension is generated when the
thick and thin filaments slightly overlap.
________ is characterized by continued attachment of myosin
heads to actin filaments due to a lack of ATP.
Tetanus
Rigor mortis
Flaccid paralysis
,age 3 of 41
Treppe ......ANSWER........Rigor mortis
A shortening of the muscle that occurs when the tension is greater
than the load is a(n)
concentric contraction.
isometric contraction.
eccentric contraction.
isokinetic contraction. ......ANSWER........concentric contraction.
Muscle fatigue
occurs when muscles are only partially able to contract.
occurs when muscle cell glycogen is depleted.
occurs when muscle cell pH increases.
, age 4 of 41
