What type of cartilage is predominantly found in symphyses?

• A. Hyaline cartilage
• B. Elastic cartilage
• C. Fibrocartilage
• D. Dense regular cartilage

Answer: (C)

Symphyses are specific types of cartilaginous joints where two bones are joined by a pad of fibrocartilage. This structure provides both strength and slight flexibility, making fibrocartilage the key type of cartilage found in these joints.

Fibrocartilage consists of a dense network of collagen fibers, which allows it to withstand tensile forces and bear weight. This property is particularly important in symphyses, such as the pubic symphysis or intervertebral discs, where the cartilage helps absorb shock and maintain stability.

In contrast, hyaline cartilage is more commonly found in places like the articular surfaces of bones and the growth plates, while elastic cartilage provides flexibility and support in structures such as the ear and the epiglottis. Dense regular cartilage, though not a widely recognized term in traditional anatomy, does not specifically refer to a distinct cartilage type associated with symphyses. Thus, the presence of fibrocartilage in symphyses is critical for its function in load distribution and resistance to pressure.
