When articular cartilage is damaged, often fibrocartilage forms instead of new hyaline cartilage. Does fibrocartilage have the same properties as hyaline cartilage? Is it likely to provide the same type of surface as hyaline cartilage? Explain. (Connects to Chapter 4)

Hey, everyone. Let's take a look at this question together, determine which statement or statements is correct regarding hyaline cartilage. And here we have statement one which says that hyaline cartilage is important since it is the main component of the joint surface. And we have statement two which says that hyaline cartilage is capable of rapid cell renewal. And we want to know is statement one correct statement two, correct both statements one and two are correct or answer choice. D neither statement is correct. Let's work this problem out together to try to figure out if statement one or statement two, both statements one and two or neither statement one or two is correct regarding hyaline cartilage. So in order to solve this question, we have to recall what we have learned about hyaline cartilage to determine if the statement is correct or incorrect. Starting off with statement one, which says hyaline cartilage is important since it is the main component of the joint surface. Well, we can recall that hyaline cartilage is important since it is that main component of the joint surface. And without that hyaline cartilage, the joint surface may not be smooth resulting in a rough surface which can cause pain or arthritis in the joint. So that hyaline cartilage is important since without it, the joint surface will not be smooth resulting in various conditions. So statement, one is a true statement which means that we can eliminate answer choice d since we know that we already have one correct statement. Next, we have statement too which says hyaline cartilage is capable of rapid cell renewal. Well, in the subject of hyaline cartilage being capable of rapid cell renewal, we can recall that the cartilage is surrounded by a Perica like fibrous membrane of which that Perica like fibrous membrane is not efficient at regenerating cartilage. So it is less efficient at that car cartilage regeneration, meaning that its recovery is slow after injury. So it is not capable of rapid cell renewal. So statement two is not a correct statement regarding hyaline cartilage, which means that only statement, one is a correct statement. So answer choice, A is the correct answer and answer choices. BC and D are all incorrect. I hope you found this video to be helpful. Thank you and goodbye.
