Which of the following statements about fibrous joints is correct?

They contain synovial fluid.

They are connected by fibrocartilage.

They allow a small degree of movement.

Cranial sutures are an example of fibrous joints.

None

What is the role of fibrocartilaginous pads in certain synovial joints?

To produce synovial fluid for lubrication

To cushion the joint and absorb shock

To strengthen ligaments

To allow rotational movement

None

Why is the presence of fibrocartilage in some joints, like the knee, critical?

It secretes synovial fluid for lubrication.

It increases the range of motion of the joint.

It provides shock absorption and improves joint congruence.

It reduces friction between ligaments and muscles.

None

Which type of synovial joint allows movement in multiple planes and axes?

Pivot joint

Saddle joint

Hinge joint

Ball-and-socket joint

None

What feature of the PCL allows it to resist anterior displacement of the femur?

Its thickened outer structure of dense connective tissue

Its ability to produce synovial fluid

Its attachment from the posterior tibia to the anterior femur

ts direct connection to the medial collateral ligament

None

What would happen if the distal tibiofibular joint were a synovial joint?

The tibia and fibula would fuse together.

Movement in the ankle would decrease significantly.

The distal tibiofibular joint would no longer function.

The stability of the lower limb would be compromised.

None

Which ligament prevents excessive adduction of the knee joint?

Posterior cruciate ligament (PCL)

Medial collateral ligament (MCL)

Lateral collateral ligament (LCL)

Anterior cruciate ligament (ACL)

None

Which of the following statements is true?

The joint capsule in synovial joints primarily reduces friction.

Ellipsoid joints allow rotation along with flexion and extension.

Ligaments increase mobility by allowing excessive movement.

Hinge joints permit only flexion and extension.

None

Which of the following best explains why different types of joints are needed in the body?

To prevent wear and tear on cartilage

To balance stability and mobility

To regulate blood flow through bones

To allow variation in bone density

None

10.

The __________ and __________ ligaments in the knee are intracapsular ligaments that provide rotational stability.

Anterior cruciate; posterior cruciate

Medial collateral; lateral collateral

Tibial collateral; fibular collateral

Patellar; oblique popliteal

None
