Its fibrous layer is made of dense irregular connective tissue that strengthens the joint

Question 10

A patient has a joint injury where the reinforcing ligaments are damaged. Which of the following is NOT a possible location for these ligaments?

Accepted Answer

Within the synovial membrane only

Question 11

Which of the following best describes the process of 'weeping lubrication' in synovial joints?

Accepted Answer

Pressure on joints squeezes synovial fluid into and out of the articular cartilage

Question 12

Which of the following is a distinguishing feature of cartilaginous joints?

Accepted Answer

Bones are united by cartilage and lack a joint cavity

Question 13

A 35-year-old patient is diagnosed with a closed suture in the skull. What is the correct anatomical term for this condition?
