18. Structure of a Synovial Joint

Which component of a synovial joint encloses the joint and helps maintain its stability during activities such as running or jumping?

• Synovial membrane

• Joint capsule

• Bursa

• Articular cartilage

What is the primary function of articular cartilage in synovial joints during sport and exercise?

• Producing synovial fluid

• Preventing infection

• Connecting bone to bone

• Reducing friction and absorbing shock

Which structure produces synovial fluid within a synovial joint?

• Ligament

• Bursa

• Synovial membrane

• Joint capsule

What is the main role of synovial fluid in a joint during physical activity?

• Strengthening the joint

• Lubricating the joint surfaces

• Attaching muscle to bone

• Storing calcium

Ligaments are essential in sport because they:

• Connect muscle to bone

• Absorb shock

• Produce red blood cells

• Connect bone to bone and provide joint stability

Which of the following best describes the function of a bursa in a synovial joint?

• Produces synovial fluid

• Reduces friction between tissues such as bone and tendon

• Connects bones together

• Absorbs nutrients

During a football match, which component of the synovial joint helps prevent the bones from grinding against each other?

• Bursa

• Ligament

• Articular cartilage

• Joint capsule

If a ligament is overstretched or torn during a rugby tackle, what is the most likely consequence?

• Increased joint stability

• Decreased joint stability and possible dislocation

• Increased production of synovial fluid

• Thicker articular cartilage

Which part of the synovial joint acts as a tough, fibrous outer layer that helps protect the joint?

• Synovial membrane

• Joint capsule

• Bursa

• Articular cartilage

Why is synovial fluid particularly important during high-intensity exercise?

• It lubricates the joint, reducing wear and tear

• It strengthens the bones

• It connects muscles to bones

• It increases bone density
