Where may fibrocartilage be found in the body?

• A. Spine
• B. Ear
• C. Knee cap
• D. Heart

Answer: (A)

Fibrocartilage is a tough form of cartilage that blends strong collagen fibers with cartilage to resist both compression and shear. This makes it ideal for areas that must absorb shock while still allowing some movement.

In the spine, the intervertebral discs are composed of a tough outer layer called the annulus fibrosus, which is fibrocartilage. This structure cushions the vertebrae and helps distribute loads when the spine bends or twists, providing stability and resilience.

The other options don’t fit because the ear contains elastic cartilage, which is elastic and flexible; the knee cap’s joint surface is covered by hyaline cartilage, which provides a smooth, slippery surface for movement; and the heart is primarily muscle tissue, not fibrocartilage.
