True regarding elastic cailage are all EXCEPT:March 2013
## Core Concept
Elastic cartilage is a type of cartilage that is rich in elastic fibers, which provide flexibility and elasticity. It is found in various parts of the body, including the external ear, epiglottis, and larynx. The presence of elastic fibers allows elastic cartilage to maintain its shape and return to its original form after deformation.
## Why the Correct Answer is Right
The correct answer, , is related to the characteristics of elastic cartilage. Elastic cartilage is indeed composed of chondrocytes, which are embedded in a matrix of collagen and elastic fibers. This composition allows for its unique properties.
## Why Each Wrong Option is Incorrect
- **Option A:** Typically, elastic cartilage is yellowish in color due to the high concentration of elastic fibers. If option A states a characteristic not typical of elastic cartilage or contradicts known facts, it would be incorrect based on that.
- **Option B:** If option B accurately describes a feature of elastic cartilage, such as its composition or function, then it would not be the correct answer to the question asking for an exception.
- **Option C:** Similar to option B, if option C is a true statement regarding elastic cartilage, it wouldn't be the correct answer to this question.
- **Option D:** Given that is the correct answer, option D must be a statement that is not true about elastic cartilage or is an exception to the characteristics of elastic cartilage.
## Clinical Pearl / High-Yield Fact
A key point to remember is that elastic cartilage provides support and maintains shape in structures that require flexibility, such as the external ear and the epiglottis. This is crucial for understanding its function and distribution in the body.
## Correct Answer: D.
