Which of the following is an example of Labile tissue?
**Core Concept**
Labile tissue is a type of connective tissue that has the ability to regenerate and renew itself quickly. This characteristic is due to the presence of a high turnover rate of cells, which allows the tissue to rapidly repair and replace damaged or lost cells.
**Why the Correct Answer is Right**
Labile tissue is found in organs such as the liver, bone marrow, and skin, where cells are constantly being replaced and renewed. The liver, for example, has a high rate of cell turnover, with hepatocytes being replaced every 300-500 days. This rapid regeneration is made possible by the presence of stem cells, which can differentiate into mature cells to replace those that have been lost or damaged.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **cartilage** is an example of stable tissue, which has a low rate of cell turnover and is less prone to injury or damage.
**Option B:** This option is incorrect because **adipose tissue** is an example of stable tissue, which has a low metabolic rate and is not capable of rapid regeneration.
**Option C:** This option is incorrect because **bone** is an example of stable tissue, which has a low rate of cell turnover and is primarily composed of a non-renewable matrix.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that labile tissue is highly responsive to injury and can rapidly regenerate, but it can also be susceptible to diseases such as cancer, which can arise from the rapid cell division and turnover.
**Correct Answer:** C. Bone marrow is the correct answer because it is an example of labile tissue, characterized by a high rate of cell turnover and rapid regeneration.
