Where Is Cartilage Present in the Human Body?

Introduction

Cartilage is widely distributed throughout the human body, especially in areas requiring flexibility, cushioning, and smooth movement. It plays a key role in joints, the respiratory system, and skeletal development.

Locations of Cartilage in the Human Body

1️⃣ Joints

Articular cartilage covers the ends of bones in synovial joints and prevents friction.

Examples:

• Knee joint

• Hip joint

• Shoulder joint

• Elbow and ankle joints

2️⃣ Spine

• Intervertebral discs contain fibrocartilage

• Acts as a shock absorber

• Allows bending and rotation of the spine

3️⃣ Rib Cage

• Costal cartilage connects ribs to sternum

• Helps in chest expansion during breathing

4️⃣ Nose

• Nasal cartilage provides shape and support

• Maintains open nasal passages

5️⃣ Ear

• Elastic cartilage forms the external ear

• Maintains ear shape

6️⃣ Respiratory System

• Cartilage rings in trachea prevent airway collapse

• Bronchial cartilage supports breathing

7️⃣ Larynx & Epiglottis

• Supports voice production

• Epiglottis prevents food from entering airway

Role of Cartilage in Radiology

• Cartilage is not directly visible on X-ray

• MRI is the best modality to visualize cartilage

• Joint space narrowing on X-ray indicates cartilage loss

Common Cartilage-Related Problems

• Osteoarthritis

• Cartilage degeneration

• Sports injuries

• Meniscus tears

🔚 Conclusion

Cartilage is present in joints, spine, ribs, nose, ears, and respiratory structures. Its health is essential for movement and breathing. Early diagnosis using MRI helps prevent long-term complications.
