Muscular atrophy involves a process in which
A. muscle fibers enlarge and increase protein filaments
B. muscles deteriorate resulting in a decrease in the size and strength of muscle tissue.
C. muscle fibers replace connective tissue.
D. muscles deteriorate in size, but remain the same shape.
i need help please
I searched Google under the key words "muscular atrophy" to get these possible sources:
http://en.wikipedia.org/wiki/Spinal_muscular_atrophy
http://en.wikipedia.org/wiki/Atrophy
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
thank you but they didn't answer me well?
i am really confused now i need more help
Answered after later repost of same question
Muscular atrophy is a condition where muscles deteriorate, resulting in a decrease in both the size and strength of the muscle tissue. To choose the correct answer, we need to understand the process involved in muscular atrophy.
To get the answer, we can go through each option and eliminate the incorrect ones based on our knowledge of muscular atrophy.
Option A states that muscle fibers enlarge and increase protein filaments. This does not align with the definition of muscular atrophy, as atrophy refers to a decrease in muscle size and strength. We can eliminate this option.
Option C states that muscle fibers replace connective tissue. This is not an accurate description of the process of muscular atrophy. Muscular atrophy involves the breakdown and loss of muscle tissue, rather than the replacement of connective tissue. We can eliminate this option too.
Option D states that muscles deteriorate in size but remain the same shape. This is partially correct, as muscular atrophy does involve muscle tissue decreasing in size. However, it is not accurate to say that the shape remains the same, as atrophy can result in changes in muscle shape due to the loss of muscle tissue. Let's keep this option for now and move on to option B.
Option B states that muscles deteriorate, resulting in a decrease in the size and strength of muscle tissue. This aligns with the definition and understanding of muscular atrophy. In this process, muscle fibers break down and lose mass, leading to the reduction in muscle size and strength. This option correctly describes the process involved in muscular atrophy.
Therefore, based on our analysis, the correct answer is B. Muscles deteriorate, resulting in a decrease in the size and strength of muscle tissue.
