Which of the following is not a labile cell –
**Core Concept**
Labile cells are a category of cells that are constantly being replaced throughout an individual's life. These cells have a high turnover rate and are found in tissues that are subject to wear and tear. Examples of labile cells include blood cells, epithelial cells, and gastrointestinal mucosal cells.
**Why the Correct Answer is Right**
Labile cells have a short lifespan and are continuously produced to replace old or damaged cells. This process is essential for maintaining tissue homeostasis and preventing disease. The constant turnover of labile cells is regulated by a balance between cell production and cell loss.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a type of labile cell. Stem cells are a type of labile cell that have the ability to differentiate into multiple cell types.
**Option B:** This option is incorrect because it is a type of labile cell. Goblet cells are a type of epithelial cell found in the gastrointestinal tract and are an example of a labile cell.
**Option C:** This option is incorrect because it is a type of stable cell. Neurons are a type of stable cell that are not constantly being replaced throughout an individual's life.
**Clinical Pearl / High-Yield Fact**
Labile cells are an essential component of tissue repair and regeneration. Understanding the differences between labile, stable, and permanent cells is crucial for medical professionals to diagnose and manage various diseases.
**Correct Answer:** C. Neurons are a type of stable cell that are not constantly being replaced throughout an individual's life.
