Explanations: answer key for all 10 questions

Q1: What is cartilage?
Answer: A smooth, flexible connective tissue
It cushions and supports.
Q2: Which cartilage covers the ends of bones in joints?
Answer: Hyaline cartilage
It is smooth and glassy.
Q3: What are cartilage cells called?
Answer: Chondrocytes
They sit in small pockets.
Q4: Why does cartilage heal slowly?
Answer: It has no blood vessels
Nutrients arrive slowly.
Q5: What does cartilage contain a lot of?
Answer: Water
Water helps absorb shocks.
Q6: What are the menisci in the knee made of?
Answer: Fibrocartilage
They act as shock absorbers.
Q7: What lubricates many joints?
Answer: Synovial fluid
It reduces friction.
Q8: Which type of cartilage shapes the outer ear?
Answer: Elastic cartilage
It bends and springs back.
Q9: Where do children's bones grow in length?
Answer: At cartilage growth plates
They harden in adulthood.
Q10: Which condition involves cartilage wearing away?
Answer: Osteoarthritis
It causes stiff, painful joints.

Cartilage Quiz – How Joints Stay Cushioned and Smooth

Cartilage is a smooth, flexible connective tissue made by cells called chondrocytes. It is rich in water and collagen, which help it absorb shocks and let bones glide.

Hyaline cartilage covers bone ends in joints, fibrocartilage forms the knee's menisci, and elastic cartilage shapes the outer ear. Synovial fluid lubricates many joints to reduce friction.

Cartilage has no blood vessels, so it heals slowly after injury. In children, growth plates of cartilage let bones lengthen, and in osteoarthritis the cartilage in joints wears away. Staying active, keeping a healthy weight and protecting joints during sport all help cartilage last longer.
