Which of the following statements is true?

The joint capsule in synovial joints primarily reduces friction.

Hinge joints permit only flexion and extension.

Ellipsoid joints allow rotation along with flexion and extension.

Ligaments increase mobility by allowing excessive movement.

None

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

The stability of the lower limb would be compromised.

The tibia and fibula would fuse together.

The distal tibiofibular joint would no longer function.

Movement in the ankle would decrease significantly.

None

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

To allow rotational movement

To cushion the joint and absorb shock

To strengthen ligaments

To produce synovial fluid for lubrication

None

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

Patellar; oblique popliteal

Tibial collateral; fibular collateral

Anterior cruciate; posterior cruciate

Medial collateral; lateral collateral

None

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

It provides shock absorption and improves joint congruence.

It increases the range of motion of the joint.

It secretes synovial fluid for lubrication.

It reduces friction between ligaments and muscles.

None

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

ts direct connection to the medial collateral ligament

Its ability to produce synovial fluid

Its attachment from the posterior tibia to the anterior femur

Its thickened outer structure of dense connective tissue

None

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

Saddle joint

Hinge joint

Pivot joint

Ball-and-socket joint

None

Which ligament prevents excessive adduction of the knee joint?

Lateral collateral ligament (LCL)

Posterior cruciate ligament (PCL)

Anterior cruciate ligament (ACL)

Medial collateral ligament (MCL)

None

Which of the following statements about fibrous joints is correct?

They are connected by fibrocartilage.

They allow a small degree of movement.

They contain synovial fluid.

Cranial sutures are an example of fibrous joints.

None

10.

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

To allow variation in bone density

To regulate blood flow through bones

To prevent wear and tear on cartilage

To balance stability and mobility

None
