Compare bone to cartilage tissue relative to its resilience, speed of regeneration, and access to nutrients.

Video transcript

Welcome everybody. Our next question says which of the following statements is true regarding cartilage tissue, A, it is able to withstand significant forces and stresses without deformation or damage. B it has a faster rate of regeneration than bone tissue. C. It is avascular or D it is less resilient than bone tissue. So let's just think through each of these answer. Choices. We're looking for the correct one. Choice A, it is able to withstand significant forces and stresses without deformation or damage. Well, it is true that cartilage can under, can withstand pretty significant force or stress, not as much as bone, but it's still very strong without damage. But the key here is the word deformation that would mean, you know, deforming of it or change in shape. But that's the whole point of cartilage is it's flexible. If you bend the top of your ear down, it will bend as opposed to bone where that won't happen. So that's why choice A is not correct since cartilage does change shape when force is put on it due to its flexibility. Choice B it has a faster rate of regeneration, bone tissue. Well, this one is also not correct. And that is due to Choice C, it is a vascular which is true. So choice C is going to be our answer. Cartilage does not have its own blood vessels. It receives nutrients and oxygen due to diffusion from nearby blood vessels and other tissues. So without its own blood supply right there, it does not heal itself. It does not regenerate as quickly as bone tissue does, which does have its own blood vessels. So that's a disadvantage for cartilage. So Choice B false because it has a slower rate of regeneration, it doesn't heal as well than bone tissue. But choice C is our correct answer. Since it is a vascular, then just to be thorough, we'll look at choice D it is less resilient than bone tissue. This one is maybe a little tricky or a little confusing. Sometimes we think of resilient in the sense of being strong with standing harm. But in this anatomical sense, resilience means returning to its original form after deformation. And of course, cartilage does that. When you bend down the tip top of your ear, when you bend the tip of your nose, it bends, it changes shape but springs back to its original shape. And of course, if you compare that to bone tissue, if you change the shape of your bone tissue, you break your bone, it is definitely not going to return to its original shape right away. So that's why choice D we might be misled by the connotation of resilience in terms of just everyday vocabulary. But in the anatomical sense, cartilage is much more resilient than bone tissue. So choice d not correct. So once again, the true statement regarding cartilage tissue choice C it is a vascular. See you in the next video.
