What is a meniscus?

1. A type of bone structure

2. A fibrous cartilage tissue in joints

3. A muscle group in the jaw

4. A condition of swollen gums

The correct answer is: A fibrous cartilage tissue in joints

A meniscus refers to a specific type of fibrous cartilage tissue found in certain joints, particularly in the knee. This cartilage has a crescent shape, providing cushioning and support during movements, which helps to absorb shock and distribute weight. In the context of dental and oral health, understanding the role of cartilage, including the meniscus, in the masticatory system can be crucial. The menisci of the temporomandibular joint (TMJ) play an essential role in allowing smooth movement of the jaw and can be involved in various disorders related to jaw function. The other options represent different anatomical structures or conditions that do not accurately define a meniscus. Bone structures, muscle groups in the jaw, and conditions like swollen gums each have distinct characteristics, which do not align with the definition of a meniscus.
