f. Elastic fibers

Hey, everyone. Let's take a look at this question together. Cut its Laxa is a rare connective tissue disorder where the skin becomes inelastic and hangs loosely in folds, determine which component of the ECM or the extracellular matrix. That is most likely the cause of this disorder. Is it? Answer choice. A the glycosaminoglycans. Answer choice B the reticular fibers. Answer choice C the elastic fibers or answer choice D the proteoglycan. Let's work this problem out together to try to figure out which of the following answer choices is the component of the ECM that is most likely the cause of Qs Laxa. So in order to solve this question, we have to recall the components of the ECM or the extracellular matrix that are associated with Q dyslexia, which is that rare connective tissue disorder where the skin becomes inelastic and hangs loosely in the faults. And we can call that in relation to Q dyslexia. Q dyslexic causes inelastic and loose skin due to degenerative changes in the elastic fibers. Since Qs Laxa is characterized by the skin becoming inelastic and hanging loosely because of the degenerative changes in the elastic fibers resulting in the skin becoming inelastic and loose. So answer choice. C elastic fibers is the correct answer and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
