Based on your knowledge of muscle tone and resting muscle metabolism, can you
explain why people who frequently work out burn more fat when lying on a couch
than a "couch potato?
Give this one a try later!
People who frequently exercise will have a heightened muscle tone, which
causes a higher resting metabolic rate. Since muscle naturally burns fat at
rest, more fat will be burned at rest if one has elevated muscle tone
How long does it take for these stepwise increases in tension to plateau?
Give this one a try later!
, These stepwise increases in tension will continue for 30-50stimulations and
then a plateau occurs
Which type of contraction is the most typical contrition of a human muscle organ?
Give this one a try later!
An isotonic concentric contraction
How can BOTOX be used to reduce the appearance of wrinkles?
Are there any legitimate medicinal uses for BOTOX? If so, what?
Give this one a try later!
Botox reduces the appearance of wrinkles by relaxing tonic muscle
contractions under the skin that cause skin to sag.
What two factors govern the amount of tension produced at the level of the individual
muscle fiber?
Give this one a try later!
The number of cross-bridges formed are dependent on the sarcomere
resting length, which correlates with the size of the muscle, and the
frequency of stimulation, which correlates with the size of stimulus
,How does myoglobin play a role in this capacity?
Give this one a try later!
is a protein much like hemoglobin that allows the cells to store oxygen and
allows for more efficient ATP production, thus reducing muscle fatigue
Can you identify some important things located in the endomysium?
Give this one a try later!
Terminal knobs, capillaries, and satellite cells are located in this loose
connective tissue
What type of cell makes endomysium?
Give this one a try later!
fibroblasts
How does this blockade affect muscle function?
Give this one a try later!
, Since acetylcholine cannot bind to nicotinic receptors, the muscle is
paralyzed
How would you define muscle tone?
Give this one a try later!
when motor units are continuously active
Upon stimulation by acetylcholine, what type of potential does the motorend plate
undergo?
Give this one a try later!
The motor end plate undergoes local/graded potentials
How does DHPR get activated?
What would happen if DHPR was inhibited by a drug?
Give this one a try later!
change in membrane potential in theT-tubules
It could not properly interact with RyR, and therefore calcium would not be
released into the sarcoplasm
